Jacaranda (Jacaranda mimosifolia) This offer is for a packet of 10 fresh seeds. Plant type: Subtropical, Deciduous Flowering Tree Hardiness: Zones 9 - 11, (8 with protection) or grown in a pot for indoor/outdoor use in all zones Size: Up to 40 ft. tall in the ground, much smaller in a pot or with pruning. Culture: Full sun, well drained sandy soil, regular water and fertilizer Season: Blooms heaviest in Spring, Sporadic blooms throughout Summer and heavy again in Fall. Native to Brazil, this spectacular tree is popular throughout mild winter areas around the world. It grows to around 40 feet tall in the ground but also makes an unusual and beautiful potted tree. It's easy to keep small with pruning and blooms well when fairly young. Easy to overwinter in an unheated garage. Jacaranda is also much hardier in the ground than most people realize and mature trees can easily take short freezes down to around 20F. Protect young trees below 25F. The delicate, ferny leaves are reason enough to grow this beauty but it's the vivid, lavender blue flowers growing in huge clusters that really grab your attention. A tree in full bloom is truly spectacular.
