The flowers are followed by smooth brown seed pods 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 Characteristics: Fast-growing. Good foliage color over a long period. Care: Golden 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. Propagation: In autumn, sow seed in a cold frame or remove suckers. Insert root cuttings or graft in winter Problems: Borers, 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. Overview Height Over 30 ft. Spread Over 30 ft.
