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.
Zone: 5 to 7
Light: Afternoon shade is recommended
Soil type: Average
pH range: Acid to alkaline
Goldenchain tree is suitable for locations wherever a small tree is needed provided the cultural conditions are suitable. Planting more than one tree, in groupings and borders for example, maximizes the flower show.
Stressed trees are prone to insect and disease problems, so plant goldenchain trees in locations that get afternoon shade.
This small tree species has a two-week spectacular flower show in May but is relatively non-descript the rest of the year. One should purchase the cultivar ‘Vossii’ since it has especially long and showy flowers.
