Jacaranda trees are tropical beauties with clusters of fragrant, purple, trumpet-shaped blooms which are 1-1/2 inch long curved with inner white throats.

The heaviest-flowering happens when grown in full sun, it can tolerate light shade and will grow quickly. Jacarandas often have an  open, irregular and oval headed growth habit; its stout trunk, gray rectangular flaked bark and alternately arranged finely divided bipinnately compound leaves that are at least a foot long and composed of 1/2 inch long narrow elliptical leaflets that give the tree a delicate fernlike appearance.

Jacarandas thrive in sandy, well-drained soils but should be watered during dry periods.  Plant in full sun with occasional deep summer watering and preferably in a soil that drains well.

Jacarandas will often survive in heavier soils but growth is slow and sometimes stunted; flowers and leaves may cause a lot of litter when they drop.

Jacaranda trees tend to form vertical suckers when pruned that distort the shape of the tree.  If pruning, only remove broken or diseased branches; so avoid pruning your Jacaranda.

COMMENTS: Pruning Jacarandas will spoil their good looks, and the tree’s shape. When you prune a Jacaranda it then sends up vertical shoots. The normal shape for a Jacaranda is that of an elegant umbrella, and the appearance of vertical branches ruins its good looks. 

Jacarandas are well-suited for cooling patios, but should not be used near pools due to the abundant leaf and flower drop.
