General Notes
A world-renowned flowering tree from the seasonally dry tropics of South America. This species famously covers Pretoria, South Africa (also known as Jacaranda City), where it has now become illegal to buy or sell a jacaranda, because of the tree’s potential to become an invasive weed. In Hawai'i, this species is also naturalized in a number of areas. In California, where it is much drier, jacaranda rarely reproduces on its own. The leaves fall in spring and return in summer as the flowers fade. Jacaranda mimosifolia has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 1 (Evaluate).
Has fragrant Flower.
Native to Argentina, Brazil, Bolivia.
