This large, fast-growing tree has spiny shoots, droopy leaves that stay sunny yellow from spring until frost, and fragrant white flowers in late spring and early summer on pendent racemes. The flowers are followed by smooth brown seedpods that are also interesting. ‘Frisia’ is one of the cultivars that is grown more for foliage than for its flowers, and it does not flower as freely as the species.
Noteworthy CharacteristicsFast-growing. Good foliage color over a long period.
CareGolden locust likes full sun in fertile, moist soil, but it will tolerate poor, dry soils. It has brittle branches, so it needs shelter from strong winds. Prune in late summer or early fall.
PropagationIn autumn, sow seed in a cold frame or remove suckers. Insert root cuttings or graft in winter.
ProblemsBorers, caterpillars, weevils, scale insects, whiteflies, leaf miners, leaf spots, wood rot, canker, powdery mildew, heart rot, and verticillium wilt can be troublesome. Suckers may be a problem.
