blue Jacaranda, fern tree, black poui, Brazilian rosewood, blue haze tree
Fast growing, deciduous tree, native to South America, with a spreading crown, bright green, fern-like leaves and purplish blue flowers in late spring or summer. Belongs to the Bignoniaceae family. Large (to about 45 cm long) leaves, twice pinnately compound, divided into many smaller (to 1 cm long) leaflets, turning yellow in autumn. Tubular flowers, 2.5-5 cm long, grouped in 30 cm long clusters, forming a blue carpet after falling to the ground. Woody, 5 cm wide, reddish brown seed pods with many small, winged seeds. Widely grown as an ornamental tree. In some parts of the world (e.g. South Africa and Queensland, Australia) Jacaranda mimosifolia is regarded as an invasive plant, posing a threat to the native vegetation.
Synonyms: Jacaranda chelonia, Jacaranda ovalifolia.
Prefers a sheltered position in full sun and very well-draining soil. Drought tolerant. Not suitable for waterlogged or clay soils. Tolerates, but does not grow and flower as well in, partial shade. No pruning required. In fact, pruning tends to destroy the natural umbrella-shape of the canopy by encouraging the tree to produce vertical shoots. Survives brief spells of moderate frosts (to about -8oC).
A gorgeous specimen or shade tree with magnificent flowers and delicate, graceful foliage, but make sure you have enough space. Not a tidy tree, so plant in a position where leaf and flower litter are not a problem. Flowers may stain hard surfaces.
