Family: Bignoniaceae(jacaranda family)
The Jacarandas are impressive trees in May when covered with clusters of blue tubular flowers. The ground below them turns rapidly blue, and some gardeners might object to that quantity of litter. A variety ‘Alba’ with white flowers, and denser foliage, is occasionally available. Native to Brazil growing to 50′ or larger. Moderate to fast growth during warm season. Bi-pinnately compound leaves hold till late in winter. Can be completely winter deciduous in colder areas. Flowers in spring are trumpet like lavender and 2″ long by 1 1/2″ wide. There are white and pink also. If the tree is given too much water, the leaves appear first, somewhat spoiling the startling effect of the flowers. The flowers are followed by woody, disc-shaped seed pods.
