Thus, the general information (Summary, Plant Needs, Functions, and Care) will be presented for both species). Each species has several cultivars that vary in stem color and foliage variegation; cultivar information will be presented for each species in the Additional Information section.

Pears are the second most important deciduous tree fruit after apple, and it has been grown in Europe since prehistoric times. Pears belong to the genus Pyrus and probably originated near the Black and Caspian Seas. French and English colonists brought pears to America and the first record of pears in the North America was in Massachusetts in 1630. Although pear is a popular fruit, it is not grown as widely as apple. Pears can be grown throughout much of North America because they tolerate a wide range of climatic conditions.

Cherries are grown in many parts of the world, but they have never gained the popularity in North America that they have in Europe and the Middle East. Cherries probably originated in the region between the Caspian and Black Seas, where trees still grow in the wild.

An orchard is a long-term investment and careful planning is essential to ensure economic success. Establishing and maintaining a peach planting to bearing age (three years) costs about $3,500 per acre. Mistakes made at planting often cannot be corrected; other mistakes that can be corrected could seriously jeopardize the economic success of the orchard. Because profit margins for commercial fruit plantings are small, orchards should be established only under the most favorable conditions for success.

Annual pruning is a critical management practice for producing easily harvested, heavy crops of high quality peaches. However, pruning is not a substitute for other orchard practices such as fertilization, irrigation, and pest control. Pruning practices vary slightly in different regions of the United States, but have changed little in the East during the past 70 years. Although pruning may vary slightly for different varieties and localities, certain general practices should be followed. The successful pruner must understand the principles of plant growth, the natural growth habit of the tree, and how the tree will respond to certain types of pruning cuts. Improper pruning will reduce yield and fruit quality.

Proper training and pruning of trees is a major component of a profitable apple orchard operation. Successful pruning is an art based upon scientific principles of tree growth and physiology and an experienced understanding of tree response to various pruning cuts and practices. Each tree is an individual and should be treated accordingly. Varieties differ in growth characteristics and response to pruning cuts, rootstocks, soil, and growing conditions. It is important that orchard designs, objectives, and goals be clearly defined and that pruning principles are developed accordingly. Mediumto high-density plantings require greater commitment to detailed training and pruning than low-density orchards and should not be attempted unless such a commitment is made.

Growing apples in the home garden can be an enjoyable and rewarding experience, but consistent production of high quality fruit requires knowledge of tree and fruit growth and a willingness to perform certain practices at the appropriate time. Virginia is on the southern fringe of the U. S. apple producing region. Most apple varieties produce the highest quality fruit when night-time temperatures are cool (less than 60°F) at harvest time. Apples grown under warmer conditions tend to be large, soft, poorly colored, and less flavorful than when grown under cooler conditions. Our warm humid summers are also conducive for infection of many diseases. For these reasons, the best Virginia apples are grown at elevations higher than 800 feet above sea level in the western part of the state. However, even apples grown in eastern Virginia usually have quality superior to apples purchased in the supermarkets.

Since the mid 1970s in the U. S., the number of apple trees per acre in new orchards has gradually been increasing. Orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. Intensification is possible by using dwarfing rootstocks that control tree size, induce early cropping, and produce large quantities of fruit relative to the amount of wood produced.

Woody plants are pruned to maintain a desired size and shape and to promote a certain type of growth. Ornamental plants are pruned to improve the aesthetic quality of the plant, but fruit trees are pruned to improve fruit quality by encouraging an appropriate balance between vegetative (wood) and reproductive (fruiting) growth.

Peach and nectarine are both members of the genus and species Prunus persica, and probably differ by only a single gene for skin pubescence (hairs on the fruit surface). One probably originated as a mutation of the other, but we do not know which came first. The species originated in China and was taken by traders from there into Persia, Greece, Italy, and other temperate areas of Europe. Peach and nectarine varieties may have yellow or white flesh. In Virginia different varieties ripen over a wide range of dates, from early June until mid-September. Varieties also differ in fruit size, susceptibility to some diseases and susceptibility to low winter temperatures, chilling requirements, and fruit disorders such as fruit cracking and split-pit. Descriptions of some of these characteristics are included in the next section of this publication.

Humans and plants depend on an adequate supply of clean water for a number of reasons, from producingfood to sustaining life. The average Virginia resident uses 826 gallons of fresh water daily (Virginia Department of Environmental Quality [VADEQ] 2008). In the Commonwealth alone, there are more than one million households that depend on well water, withdrawing more than 50 billion gallons annually (Virginia Department of Health 2008). For groundwater replenishment, we depend largely on recharge (water moving from the surface to groundwater) from infiltration of precipitation through permeable surfaces in the environment — an important part of the natural water cycle (VADEQ 2010).

The area where an organism lives and meets its basic needs for food, water, cover, and space to survive is called its habitat. Each species of wildlife has different habitat requirements.

The value of an attractive landscape to a home’s perceived value has often been stated at 15 percent. Is this figure reliable, and what landscape features do contribute to the value of a home? How does a landscape contractor convince his/her client to spend a significant portion of a home’s construction budget on landscaping, and is this a wise investment? How can a homeowner feel justified by spending thousands of dollars to landscape a newly constructed house? Or, will thousands of dollars worth of landscaping, significantly increase the “curb appeal” of a home for sale? To answer these questions, researchers conducted a seven-state survey of attendees at consumer home and garden shows to determine consumer perspective on how plant size, type, and design sophistication in a landscape affect the perceived value of a home (Behe et al., 2005).

Select only those plants that appear to be free of pests. Check the undersides of the foliage and the junction of leaf and stem for signs of insects or disease. Select plants that look sturdy, clean, and well-potted. Choose plants with healthy foliage. Avoid plants with yellow or chlorotic leaves, brown leaf margins, wilted foliage, spots or blotches, or spindly growth. In addition, avoid those with torn leaves. Plants that have new flower and leaf buds along with young growth are usually of superior quality.

In 2007, Virginia Cooperative Extension (VCE) developed the America’s Anniversary Garden to help individuals, communities, and groups commemorate America’s 400th Anniversary with a signature landscape, garden, or container planting. These signature gardens have red, white, and blue color schemes. Although the commemoration has passed, this guide continues to be useful for creating a patriotic garden.

This publication covers key questions to consider when planning a vegetable garden.

El objetivo de la jardinería intensiva es cosechar la mayor cantidad posible de productos en un espacio limitado. Las huertas más tradicionales constan de largas hileras de hortalizas muy separadas entre sí. Gran parte de la superficie de la huerta está ocupada por el espacio entre las hileras. Una huerta intensiva minimiza el espacio desperdiciado. La práctica de la huerta intensiva no es solo para los que tienen un espacio limitado en el jardín; más bien, una huerta intensiva concentra sus esfuerzos de trabajo para crear un entorno ideal para las plantas, lo que brinda mejores rendimientos.

Varieties include both the slicer or fresh salad type and the pickle type (which can also be used fresh); vined, dwarfvined and bush varieties; all female or all-female seedless (no pollination required); burpless; and, various mixtures of these characteristics. Disease resistance is available in many varieties.

Lettuce, a cool-season vegetable crop, is one of the easiest to grow. Lettuce withstands light frost; however, sunlight and high summer temperatures usually cause seedstalk formation (bolting) and bitter flavor. Slow-bolting or heat-resistant varieties are available and are recommended for extending the lettuce-growing season.

Onions are often grouped according to taste. The two main types of onions are strong flavored (American) and mild (often called European). Each has three distinct colors, yellow, white, and red. In general, the American onion produces bulbs of smaller size, denser texture, stronger flavor, and better keeping quality than European types. Globe varieties tend to keep longer in storage.

Tomatoes are valuable garden plants in that they require relatively little space for large production. Each standard tomato plant, properly cared for, yields 10 to 15 pounds or more of fruit.Diane Relf, Retired Extension Specialist, Horticulture, Virginia Tech Alan McDaniel, Extension Specialist, Horticulture, Virginia Tech Ronald Morse, Former Associate Professor, Horticulture, Virginia Tech Reviewed by John Freeborn, Assistant Master Gardener Coordinator, Horticulture, Virginia Tech

Landscapes are composed of plants that form ceilings, walls, and floors spaces. Groundcovers serve as attractive carpets of foliage that cloak and beautify our landscape “floors” (fig. 1). A groundcover is a low-growing plant species — 3 feet tall or shorter — that spreads to form a relatively dense layer of vegetation. In covering bare soil, groundcovers reduce soil erosion and provide habitat for insects and other animals, along with a host of other positive environmental effects.

Specialty cut flowers are one of the most profitable field crops you can grow. Lynn Byczynski, editor of Growing For Market newsletter (see Resources section), estimates a value of $25,000 to $35,000 per acre for field-grown cuts. The most basic requirements are at least half an acre of open, arable land, a rototiller, and, of course, time and effort. This publication is directed to those new to market gardening, but commercial vegetable growers, tobacco farmers, and young people interested in summer income are all potential candidates. Even grain and livestock farmers have increased profitability in their operations by adding cut flower production. For many greenhouse and nursery operations, mid-summer business is slower, relative to spring. A field-grown cut flower business is a viable option to fill in the summer production and cash flow gap.

What is a shrub? A shrub is generally considered a multi-stem woody plant that is less than 15 feet tall. Of course, this and other plant size categories are definitions contrived by humans to categorize nature. What is the difference between a large shrub and a small tree? In many cases, there is none. A shrub does not become a tree just because it grows higher than 15 feet. Classifying plants into ground cover, shrub, and tree designations are aids to allow us to conveniently classify and describe plants, albeit with a significant amount of ambiguity.

Healthy plants are less susceptible to attack by pests, and good cultural practices can reduce pest outbreaks.

Something is wrong with your plant. What’s the cause? You can begin to determine the cause of the problem by taking on the role of Sherlock Holmes – be a keen observer and ask many questions. Diagnosing plant problems is often a difficult task. There can be many different causes for a given symptom, not all of them related to insects or diseases. The health of a plant may be affected by soil nutrition and texture, weather conditions, quantity of light, other environmental and cultural conditions, and animals, including humans. Complicating this scenario is the fact that any two of the above factors can interact to give rise to a problem. For example, a prolonged period of drought may weaken plants so that they are more susceptible to pests; this is typically observed with boxwoods.

Landscaping is an integral part of our culture and plays an essential role in the quality of our environment, affecting our economic well-being and our physical and psychological health. If we are to keep our communities strong and prosperous, we must take responsibility for our environment.

Los árboles y arbustos necesitan nutrientes para crecer y estar sanos. Los tres nutrientes más importantes son nitrógeno, fósforo y potasio. Un análisis de suelos es siempre la mejor manera de saber qué nutrientes se necesitan y la cantidad necesaria de cada uno.

Using trees as living screens can easily enhance living and working spaces. Before selecting trees for screening, first determine the screen’s purpose, whether functional or environmental. Screening can be used to define an area, modify or hide a view, create privacy, block wind, dust, salt and snow, control noise, filter light, and direct traffic flow.

To grow, all trees require air, light, water and nutrients. Some trees can survive over a wide range of climatic and soil conditions, whereas others are very site specific. Both wet and dry sites present establishment and growth challenges, making selection of the right tree for the right site very important.

Trees can become a dangerous liability when they are planted near utility lines and their mature size leads to conflicts with the utility lines. Trees can damage utility lines, disrupt power delivery, and create hazardous conditions. Utility companies expend significant resources managing tree conflicts through pruning and removal. Despite the potential for these conflicts, property owners often desire trees near utility lines for amenity and privacy. To prevent recurring conflicts with utility lines, trees with compatible mature size should be planted near utility lines. In this publication are recommendations for minimizing tree conflicts with utility lines along with an extensive list of utility line compatible tree species suitable for landscapes in Virginia and the Mid-Atlantic region.

The nursery industry in Virginia has enjoyed an extended period of growth and expansion. Consequently, there is considerable interest in and some potential for new business opportunities in the industry. Another consequence of this period of economic growth is an increase in competition within the industry to supply the growing demand for landscape plants. Those interested in getting into the nursery business are strongly encouraged to invest their time and energy into learning as much as they can about the modern nursery industry, and the many options now available in nursery production, before they invest any money in facilities and operations.

Increased fuel costs and colder than normal winters make heating costs a significant burden on many greenhouse operations. So, how can growers deal with high energy costs in the greenhouse? This publication covers energy conservation, alternative fuel choices, growing temperatures and production practices.

Globe artichoke (Cynara scolymus L.) is an herbaceous perennial that is grown for its tender, edible, immature flower buds. The globe artichoke should not be confused with Jerusalem artichoke, another member of the composite family native to North America, which is grown for its fleshy tubers. Globe artichoke plants can become large: four to five feet tall and wide, with long, heavily serrated silvery green leaves (Figure 1a).

The most effective form of plant disease control in the landscape is prevention. Disease prevention can be as simple as choosing the right plant for the right place at planting time. This fact sheet was developed as a guide to shrubs that generally experience few problems in Virginia landscapes. Using these species for new plantings should help you avoid troublesome disease and insect problems in your landscape.

La forma más eficaz de controlar las enfermedades de los cultivos en nuestro jardín es la prevención. La prevención de enfermedades puede ser tan sencilla como elegir el cultivo adecuado para el lugar adecuado al momento de cultivar. Esta hoja informativa fue desarrollada como una guía de los arbustos que generalmente experimentan pocos problemas en los paisajes de Virginia. El uso de estas especies para las nuevas plantaciones debería ayudarle a evitar problemas de enfermedades e insectos en su jardín.

Many of the tree species commonly planted in Virginia landscapes suffer from disease problems. Although some diseases can be cured, most must be controlled on a preventative basis. The best option for new plantings is to choose species that have a low risk of developing disease. Listed below, in alphabetical order, are some choices of problem-free trees for Virginia landscapes.

Your Soil Test Report and related Soil Test Notes referred to on a report will help you assess your plant’s need for fertilizer and lime.

This guide lists vegetable varieties that are available and are adapted to the mid-Atlantic region, gives an overview of cultural practices, and list chemicals recommended to manage pests, diseases and weeds in vegetable crops. New varieties of vegetables are constantly being developed throughout the world. While all efforts are made to have comprehensive lists, not all varieties that are adapted will be listed.

Virginia’s food system directly impacts the survival and viability of farms and farmland; the economic development of rural and urban communities; the care, restoration, and resilience of ecological resources such as local waterways; and critical health issues. We use the language of community, local, and regional food systems to broadly define a complex and interconnected set of systems and pathways that comprise sustainable food production, processing, distribution, consumption, and waste management to bring about social, economic, and ecological change that benefits all residents.

As it is every year at this time, it’s finally spring and the grass is growing. What is different about this year though, is that the kids are home. It might seem like a good idea to send them outside to do some yard work while practicing social distancing—and it is! Fresh air and exercise can help ease the stress of being cooped up inside for months on end.

Goldenchain tree is a small tree that is primarily noted for its very showy pendulous flowers (16 inches plus in May). This species is best grown in zones 5 to 7 and generally requires afternoon shade. Plants in full sun are often stressed and succumb to pest problems. ‘Vossii’ is a long-flowered cultivar.

Hinoki falsecypress is a medium to large conifer. There are numerous cultivars that are more popular and prevalent in the nursery trade than the species. However, the species is a very beautiful conifer and well worth the hunt in garden centers or mail order nurseries. In my opinion, the hinoki falsecypress (species, not a cultivar) is more desirable than the sawara falsecypress (Chamaecyparis pisifera species, not a cultivar) since hinoki falsecypress foliage is denser and brighter green, and the bark is a brighter red-brown color. Cultivars vary in size (growth rate), foliage size and color, and form.

Japanese cryptomeria is a handsome medium to large conifer with a conical to narrow conical form. This species is fast growing and is relatively popular in the trade. If lower limbs are removed, one can observe a beautiful orange-brown bark (on most trees). The foliage tends to turn brownish on the south side of the plant in winter due to desiccation; however, foliage will turn green in spring. Japanese cryptomeria does have a few disease problems, although these are not considered a major issue at this point in time.

Japanese stewartia is a strikingly beautiful small tree. It has very showy white flowers with gold-colored stamens in June; bright maroon-red fall foliage color; and with age develops bark with a patchwork of brown, orange-brown, and cream colors. Bark characteristics vary from tree to tree and some trees have lustrous bark.

Japanese zelkova is a medium to large shade tree with a distinct vase shape. This species is quite drought and heat tolerant; its use as a street tree species is testimony to its toughness. Fall foliage colors range from fair to quite good (orange to bronze-red to maroon) and will vary from tree to tree (seedling-grown trees) or from cultivar to cultivar.

Katsuratree is a magnificent medium to large shade tree. Its accolade-deserving qualities are its form, beautiful foliage, and bark. Seedling-grown trees have a variable form ranging from upright oval to pyramidal to wide spreading. This species has a tendency to develop major branches near ground level, and if one has ample space, such low slung trunks give the lower portion of the tree a majestic “octopus-like” appearance.

Lacebark pine is a medium (sometimes large) conifer species that has strikingly beautiful bark. Bark is a camouflage-like patchwork of greens, silvery-white, creams, browns, and red-browns. There is a great amount of tree to tree variation in bark color; patchwork of colors begins to appear on approximately 2 inch diameter branches.

Leyland cypress is a fast-growing conifer that is one of the most popular landscape conifers in the eastern U.S. In addition to its vigor, this species is relatively drought tolerant and can be pruned into a hedge.

Background: Hops were grown in Virginia even in the days of Thomas Jefferson, but production eventually shifted away from the east coast in favor of the Pacific Northwest. For the past few decades, hops have not been grown commercially on a substantial level in Virginia. However, beginning several years ago when the craft brewing industry surged, renewed interest in hops production led to a rapid increase in the number of hobby and commercial hops growers. A fall 2014 survey showed approximately 50 growers in the state, but as of 2015 many new growers have been added to the ranks. Much of the production is clustered in Northern Virginia and the I-81 and I-64 corridors, but growers can be found in all regions of the state stretching from Southeast to Southwest Virginia.

Mimosa is a fast-growing small tree with very attractive pink pin cushion-like flowers in summer. This species has tropical-like foliage (bipinnately compound foliage with very small leaflets) that confers a very fine texture to the tree.

Norway spruce is a medium to large conical conifer. When young (first 10 years or so), the plant is stiffly conical. With age, the secondary branches hang from the primary horizontal branches.

Paperbark maple is a small tree with exceptionally beautiful peeling cinnamon-colored bark. Most branches, those that have a diameter about one-half inch and larger, will have peeling (exfoliating) orange-brown bark.

Wine making has increased in popularity as a hobby for home gardeners who have taken the science and craft beyond the grape vineyard to the bramble patch, vegetable garden, and flower garden. This article describes the basic steps used in making wine from fruits or vegetables grown in the home garden.

Red buckeye is typically a multi-trunk small tree (large shrub). Its claim to fame is the red flowers that cover the plant in April/May. Flower stalks (panicles) are about 8 inches long with 2 inch long red tubular flowers. Flowers are pollinated by ruby-throated hummingbirds.

River birch is a fast-growing shade tree species. As the common name implies, river birch trees tolerate wet soils and are a very suitable species for portions of the landscape that characteristically have moist soil, such as low areas or in poorly drained soils.

Saucer magnolia is generally a small (occasionally medium) multi-stem tree that is known for its outstanding flower display in March (February in southern U.S. and April in northern U.S.). Flowers are about 8 inches in diameter; outer sides of petals (actually called tepals; about 9 tepals) are various shades of pink-purple while inner sides of tepals are white.

Sawara falsecypress is a medium to large conifer. There are numerous cultivars that are more popular and prevalent in the nursery trade than the species. Cultivars vary in size (growth rate), foliage type and color, and form. Many of the cultivars are considered “dwarf” since they do not attain the mature size of the species.

According to the United States Department of Agriculture 2012 Census of Agriculture, sales from greenhouse-grown food crops equaled around $800 million in the U.S. Crops grown included tomatoes, lettuce, cucumbers, peppers, and berries, with hydroponic production operations making up about 64% of the total production (cwt) (USDA Census of Agriculture, 2012). Demand for greenhouse-grown produce continues to increase, providing growers with unique opportunities to tap into this expanding market. Although greenhouse systems provide a more protected environment than field-grown systems, it is important to understand the unique food safety risks and possible sources of contamination when growing produce in these systems. Identifying food safety hazards are necessary to implementing practices that reduce the risk of contamination during the pre-plant, production, harvest, and post-harvest handling stages. Use the checklist below to guide you in asking important questions targeting possible risks at each of the greenhouse system stages.

Scotch pine is a medium tree. Like most pines, the first 20 or so years of its life it has a conical shape and with maturity it loses its lower limbs and has an irregular flat topped or oval shape. Scotch pine has a relatively showy orange colored bark (with the exception of the lower trunk). It is also relatively drought tolerant, thus it is suitable for landscape sites that tend to be dry.

Sourwood is a small slow-growing tree although forest specimens exceed this small status. This species is certainly worthy to be a specimen plant (sufficient attributes to be featured as a focal point). Sourwood has beautiful lustrous foliage in the growing season which turns a bright maroon to pink-red in the fall.

Star magnolia is a small multi-stem tree that is known for its outstanding flower display in March (February in southern U.S. and April in northern U.S.). Flowers are about 3 to 4 inches in diameter and fragrant; outer sides of petals (actually called tepals; about 12 to 18 tepals) are white or blushed with pink while inner sides of tepals are white.

Umbrella-pine is a beautiful slow-growing conical conifer. Its beauty is mostly derived from the unusual texture that is imparted by the glossy dark-green needles that occur in whorls along the stem.

"Low Tunnels in Vegetable Crops: Beyond Season Extension" is a comprehensive document that delves into the multifaceted benefits of micro tunnels in vegetable cultivation, encompassing not only extended growing seasons but also improved yield, pest management, and resource efficiency, making it an essential resource for modern sustainable farming.

Washington hawthorn is a small tree (single or multiple trunks) with showy white flowers in June. Trees produce an abundance of persistent glossy bright red fruit (about 0.25 inches in diameter) that result in a spectacular fruit display that persist into winter months.

Plant growth regulators (PGRs) are chemicals that are designed to affect plant growth and/or development (figure 1). They are applied for specific purposes to elicit specific plant responses. Although there is much scientific information on using PGRs in the greenhouse, it is not an exact science. Achieving the best results with PGRs is a combination of art and science — science tempered with a lot of trial and error and a good understanding of plant growth and development. good understanding of plant growth and development.

American hornbeam, also called blue beech, musclewood, water beech, and ironwood, is a small to medium tree. In its youth, and even sometimes at maturity, this species tends be multi-trunked and densely branched. It also tends to develop major branches near ground level which can be a desirable or undesirable characteristic depending on how this species is intended to be used in the landscape.

Beeches, both the American and European species, are large stately and noble trees. They have a smooth sensuous dark gray bark that is exceptionally attractive. Unfortunately, this feature often beckons graffiti practitioners to denigrate trees by carving their initials on trunks.

Native to the Southern United States, the Sabal minor or Dwarf Palmetto is a smaller and much shorter cousin to the familiar Sabal palmetto that lines the streets and palisades of cities in the Deep South, where the fronds were once cut to make ladies’ hand fans. Part of the Dwarf Palmetto’s native range includes the extreme southeastern portion of Virginia. As a result, S. minor is one of the most cold-hardy palms that can be grown in the Commonwealth of Virginia.

The emerald ash borer (Agrilus planipennis Fairmaire) is a wood-boring beetle native to eastern Asia and is now considered the most destructive forest pest ever seen in North America. Since its discovery in Michigan in 2002, it has killed tens of millions of native ash (Fraxinus spp.) trees in the United States and Canada. This destruction has already cost municipalities, property owners, and businesses tens of millions of dollars in damages.

Chinese elm is a medium to large fast-growing shade tree. This species is quite tolerant of drought and poor soil; hence, it has been extensively used in urban situations. There are numerous cultivars; cultivar selection criteria include cold hardiness, form, growth rate, foliage characteristics, and bark showiness.

Have you ever wondered if it is possible to enjoy the beauty of bulbs in the middle of winter? The answer is definitely yes! Many people are familiar with the hourglass-shaped vase filled with water and topped with a hyacinth bulb, or a low bowl filled with several Paper White narcissus, and the popular boxed amaryllis bulb as a welcome winter holiday gift. Most bulbs can be forced but additional planning is required in order to have a successful period of blooms.

Chinese pistache is a medium-size shade tree. It is quite tolerant of full sun, hot, and dry conditions (once established). This species has separate male and female plants (dioecious); female plants (if male trees are present) will produce clusters of reddish pea-size fruit that are somewhat attractive.

This publication features small, medium, and large flowering shrubs (five of each category) with photos. All photos are by the author. There are at least eight shrubs from each category noted in a table (without photos) at the end of this publication. All shrubs — featured or in the table — are landscape worthy and are especially suited to landscapes in Virginia and the Mid-Atlantic States.

Douglasfir is a large and stately narrow conical conifer that is native to the Pacific Northwest (P. menziesii var. menziesii) and Rocky Mountains (P. menziesii var. glauca). Trees in native habitats are often taller than 100 feet; however, landscape trees rarely exceed 50 feet.
