Best in sandy, fertile, well-drained soils in bright light. Likes heat and humidity. Keep soils evenly moist year around, and never allow soils to dry out. Bring pots indoors each fall before frost for overwintering in a bright cool location. Young plants usually do not flower.
Jacaranda mimosifolia, commonly called jacaranda, is native to Argentina and Bolivia. It is a deciduous tree that grows 25-50’ tall in its native habitat. In tropical and subtropical climates, it puts on a spectacular flowering display in spring to summer wherein blue-purple flowers cover the tree with bloom, forming pools of blue on the ground as they fall. Flowers (to 2” long) appear in 12-inch terminal panicles in spring and early summer. Flowers give way to flattened 2-inch capsules, each containing numerous winged seeds. In St. Louis, jacaranda may only be grown in containers. Container plants often do not bloom, so in areas such as St. Louis, it is grown primarily as a foliage plant. Features large bipinnate compound fern-like leaves (to 18” long) with tiny 1/2-inch leaflets. Sometimes commonly called fern tree. Synonymous with Jacaranda acutifolia.
Genus name comes from the Latinized Brazilian name.
Specific epithet means with leaves that resemble those of mimosa.
