description
Jacaranda trees are medium to large, deciduous or evergreen trees. They have bipinnate leaves and bell-shaped, predominantly purple to mauve colored flowers. A few species have white flowers.
Jacaranda as a tree genus used for forestry
The wood only plays a limited role. Some species are grown as useful crops. The wood of these trees is valuable and richly patterned. The most important commercially used tree is Jacaranda filicifolia . The wood of the other species is too soft to be used as timber. Jacaranda mimosifolia means rosewood tree in German ; the wood known as rosewood , however, comes from the legume genus Dalbergia .
Jacarandas as an ornamental plant
Their striking bloom, which lasts for about two weeks, has resulted in them being grown as ornamental plants in many climatically suitable regions. The rosewood tree ( Jacaranda mimosifolia ) is one of the trees of this genus that are particularly frequently planted .
In Central Europe, where the trees do not thrive outdoors due to their sensitivity to frost, they are very rarely offered as houseplant . Jacaranda mimosifolia seeds , which are sold by seed companies, germinate relatively easily after 7-10 days. However, the rosewood tree rarely blooms as a houseplant. Flowers are only set when the plant reaches a height that makes it unsuitable as a houseplant.
