- Description
-
The Golden Chain Tree is a small, deciduous, flowering tree or large shrub in the bean family that grows to 30 feet tall, with an equal spread, at maturity. It has smooth bark, dark green spreading branches and pendulous and pubescent twigs. The leaves are generally trifoliate and oval with long petioles, smooth on the upper side and hairy on the underside. The pea-like, fragrant, yellow flowers bloom during May and June. The genus name is the Latin name. The species name means resembling the genus Anagyris.
Golden Chain Tree does best in organically rich, medium moisture, well drained soil in full sun, but does tolerate partial shade. The tree does not do well in the heat and humidity of the deep South (south of USDA Zone 7) and prefers climates where both summer and winter temperature are moderate.
Golden Chain Tree can be pruned to shape as a flowering hedge. If you are forming it as a small tree, remove root suckers as they appear. Also remove the seedpods as they are not ornamental and are poisonous. Wear gloves when working with this plant.
Diseases, Insect Pests, and Other Plant Problems:
Twig blight is an infrequent but serious disease. Canker and leaf spot can be problems. Watch for aphids and mealybugs.The tree is short-lived and does not tolerate heat. Full drainage is especially important.
