The most spectacular flowering tree in the world. For those who live where it can thrive. Jacaranda mimosifolia, the Blue Jacaranda, is considered by many horticulturists and travelers to be the most spectacular flowering tree on Earth. In late spring, before a single leaf has opened, it covers itself in dense masses of tubular lavender-blue flowers that last for weeks, creating a display of color so saturating and so pervasive that streets lined with them in South Africa, Australia, and California become destinations for people who travel specifically to see them bloom. The feathery, fern-like compound leaves that follow are beautiful in their own right. If you are looking to buy Jacaranda seeds or grow Blue Jacaranda from seed, this is the tree that turns a warm-climate garden into something people remember. Masses of lavender-blue tubular flowers covering the entire canopy before leaves emerge in late spring Delicate, fern-like compound leaves providing lacy, filtered shade through summer One of the most recognizable and celebrated flowering trees in warm-climate horticulture worldwide Fast-growing in warm climates, reaching flowering size in 7 to 10 years from seed Seed-grown trees take longer to bloom than grafted nursery trees but develop stronger root systems Things you probably did not know about the Blue Jacaranda Pretoria, South Africa is called the Jacaranda City. Over 70,000 Jacaranda trees line the streets of Pretoria, South Africa, and when they bloom in October the entire city turns violet-blue. The blooming of the Jacarandas marks the beginning of exam season at the University of Pretoria, giving rise to a student tradition that if a Jacaranda flower falls on your head, you will pass your exams without studying. The trees are not native to Africa but have been so thoroughly adopted that they define the city's identity. The flowers fall as a carpet rather than gradually. Jacaranda flowers drop en masse when they finish, creating a blue-purple carpet on the ground beneath the tree that is often described as more beautiful than the tree itself. The carpet of fallen flowers can persist for days in calm conditions, creating a double display of living flowers above and fallen flowers below simultaneously. The wood is used for musical instruments in its native South America. Jacaranda wood is dense, fine-grained, and produces excellent acoustic properties when used for guitar backs, sides, and fingerboards. Brazilian Rosewood, one of the most prized tonewoods in the world, is actually a Jacaranda species, Jacaranda mimosifolia's relative Dalbergia nigra. The acoustic properties of Jacaranda wood have been appreciated by instrument makers for centuries. It can be grown as a container plant in cold climates. In zones colder than 9, Blue Jacaranda can be grown in large containers, moved indoors in winter, and brought outside in summer. Container-grown specimens rarely reach full size but can flower and provide the distinctive foliage texture in climates where outdoor planting is not possible. Many enthusiasts in zones 7 and 8 manage Jacaranda as a large patio plant with winter protection.
