Jacaranda mimosifolia
Hard · Experienced growersAbout Purple Jacaranda
The Purple Jacaranda is a fast-growing deciduous tree famed for its spring display: fern-like compound leaves fall away as clusters of trumpet-shaped lavender-purple flowers blanket the canopy, then carpet the ground below in violet. Native to the subtropical woodlands of Argentina and Bolivia, it has become a beloved ornamental shade and street tree worldwide, from Pretoria to Los Angeles to Sydney. Mature trees reach 30 to 50 feet with a broad, spreading crown, followed by flat, woody seed pods. It thrives in full sun with well-drained soil and, once established, tolerates drought well.

History
The Purple Jacaranda is native to the dry subtropical woodlands of northwestern Argentina and southern Bolivia, where it grows scattered among other deciduous trees along riverbanks and rocky slopes. Its genus name comes from a Guaraní word for the tree, long prized by South American woodworkers for its fragrant, easily carved timber. In the nineteenth century, botanic gardens and colonial plant collectors carried the Purple Jacaranda far beyond South America, and by the early twentieth century it had been planted as an avenue tree across the subtropical world. Nowhere took to it more than Pretoria, South Africa, where more than seventy thousand jacarandas were planted along city streets starting in the 1880s, earning it the nickname the Jacaranda City. Because the trees burst into full violet bloom each October and November, exactly as the University of Pretoria's academic year draws to a close, generations of students have walked beneath purple-carpeted streets watching for falling flowers, holding that a blossom landing on your head or being caught before it touches the ground brings good luck on final exams. The same trees now line boulevards from Buenos Aires to Los Angeles to Sydney, their brief but brilliant flowering season marking the turn of the seasons in cities half a world from where the species first grew wild.
Symbolism & meaning
What It Symbolizes
In Pretoria, South Africa, nicknamed the Jacaranda City for its tens of thousands of purple-blooming trees, university students have long held that catching a falling jacaranda blossom, or having one land on your head, brings good luck on final exams. Because the trees flower each October and November, exactly as the academic year ends, generations of students have walked beneath purple-carpeted streets watching for falling flowers as a sign of good fortune to come.
- Good Fortune — In Pretoria, South Africa, students have long believed a jacaranda blossom falling on your head, or catching one before it hits the ground, brings luck on final exams — the trees bloom each year exactly as term ends.
- Renewal — Its dramatic transition from bare branches to a canopy of solid violet, before a single leaf appears, has made the Purple Jacaranda a seasonal symbol of transformation and renewal in cities across the Southern Hemisphere.
Where the Name Comes From
The genus name Jacaranda comes from a Guaraní word describing the tree's fragrant, richly grained timber, long used by South American woodworkers. The species name mimosifolia refers to its fern-like, mimosa-like compound leaves. The common name Purple Jacaranda simply reflects its signature violet flowers.
