Horticulture

Golden-ball lead tree is suitable as a patio tree due to its small size. The flowers are attractive. Growth rate is moderate with irrigation. This species tolerates a variety of soils and will grow in rocky sites. The plants are hardy to at least 10° F (-12° C). Prune when young to encourage a tree form. Twigs and sometimes limbs will periodically die and can be removed. Fallen leaflets and fruits create minor litter issues.
