Jacaranda mimosifolia 'Alba': 'Alba' Jacaranda

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, and Deborah R. Hilbert


Soft, delicate, fernlike, deciduous foliage and dense terminal clusters of pure white, lightly fragrant, trumpet-shaped flowers make this large, spreading tree an outstanding specimen planting. The striking blooms can appear any time from April through August (most often May), and are sometimes present before the fresh, new, light green leaves appear in spring. Flowering is reportedly best following a winter with several nights in the upper 30's. Jacaranda may flower best when grown in poor soil. Jacarandas can reach 25 to 40 feet in height with an equal or greater spread, and the bent or arching trunks are covered with light grey bark.

Use and Management

The light, dappled shade makes jacaranda well-suited for cooling patios, but it probably should not be used near pools due to the abundant leaf and flower drop. Jacaranda makes an ideal street tree, creating a spectacular sight when in full bloom. The arching branch habit is ideal for creating a canopy over a street or boulevard. Be sure to plant only those trees which have one central trunk and major limbs well-spaced apart for street tree and other high-use areas. Unpruned trees can become hazardous as they split apart at the crotches. Once properly trained and pruned, jacaranda is fairly strong-wooded and less messy than royal poinciana.

Small jacaranda trees can tolerate light shade and will grow quickly, but they will have the heaviest flowering when growing in full sun. They thrive in sandy, well-drained soils but should be watered during dry periods. Prune branches so they remain less than half the diameter of the trunk to help keep the plant intact and increase durability.

Propagation is by softwood cuttings or grafting. Seedlings often take a long time to bloom so grafted trees or those rooted from cuttings are preferred.


No pests are of major concern.


Mushroom root rot is a problem on poorly-drained soil.
