General Culture:

Easily grown in average, dry to medium, well-drained soil in full sun. Adapts to a wide range of soils. Tolerates drought and many city air pollutants. Not as winter hardy as the species, and may be best planted in a protected location in USDA Zone 5.

Noteworthy Characteristics:

This golden raintree cultivar is a small, open-branching, irregularly-shaped, deciduous tree with a rounded crown which typically grows 30-40' tall and as wide. Features pinnate or bipinnate, feathery, compound leaves (to 18" long), each leaf having 7-17 irregularly lobed leaflets. Leaves emerge pinkish bronze to purplish in spring, mature to a bright green in summer and turn yellow (quality variable) in fall. Bright yellow flowers (1/2" wide) appear in long, terminal, densely-branched panicles (12-20") in late August to September. Cultivar name is in reference to the September flowering period (species flowers in early summer). Falling blossoms may or may not resemble "golden rain", but the fallen blossoms often form an attractive golden carpet under the tree. Flowers give way to interesting, brown, papery seed capsules which somewhat resemble Chinese lanterns.

Problems:

No serious insect or disease problems. Some susceptibility to root rot, leaf spot and canker.

Uses:

Can be used as a small shade tree or street tree or as a specimen tree in lawns or terraces.
