Silver maple (Acer saccharinum) is a large fast-growing species that is not suited to most landscapes since it is prone to several pests and is relatively weak wooded. It has a fair fall foliage color at best. This species is suitable for waterside plantings since it tolerates wet soils but one must recognize its shortcomings.
Red maple has a profusion of small, red flowers in early spring. This species’ fast-growing nature, flower and fall foliage color display make it a desirable landscape species especially for someone who does not want to wait a long time to have a medium sized tree. One should investigate the characteristics of available cultivars before purchasing a plant.
