Jacaranda mimosifolia is native to the seasonally dry forests of Bolivia, Paraguay, and northern Argentina, where it drops its leaves during the dry months and then, with almost theatrical timing, erupts into flower before the new foliage arrives. The name of the species, mimosifolia, describes those leaves well: large, fern-like, and bipinnate, they give the tree an airy, graceful quality even at its full fifty-foot height. In the subtropics, young trees grow fast, sometimes gaining ten feet in a season, though growth slows in cooler climates. Mature trees develop a distinctive vase-shaped crown, wide and generous.

The purple-blue flowers, which draw bees and belong botanically to the trumpetvine family Bignoniaceae, have made Jacaranda one of the most celebrated ornamental trees in warm regions worldwide. It performs best in full sun with well-draining, slightly sandy and acidic soil — clay and loam are acceptable, but waterlogged ground is not tolerated. The wood is somewhat brittle and storm damage is possible; planting away from pools and patios also avoids the inevitable litter of fallen flowers, though many gardeners consider that carpet its own kind of reward. In colder climates where the tree will never bloom, young plants grown in containers still offer exceptional foliage.
