Jacaranda mimosifolia has been widely planted elsewhere because of its attractive and long-lastingviolet-coloredflowers. It is also known as thejacaranda,blue jacaranda,black poui, orfern tree. The blue jacaranda has been cultivated in almost every part of the world where there is no risk of frost established trees, however, tolerate brief spells of temperatures down to around 7 c (19 f).In the us, in areas where winter temperatures can dip to 12 c (10 f) for several-hour periods, the mature tree survives with little or no visible damage. Even when young trees are damaged by a hard frost and suffer dieback, they will often rebound from the roots and grow in a shrub-like, multi-stemmed form.The tree grows to a height of up to 20 m (66 ft). Its bark is thin and grey-brown, smooth when the tree is young but eventually becoming finely scaly. The twigs are slender and slightly zigzag they are a light reddish-brown. The flowers are up to 5 cm (2.0 In) long, and are grouped in 30 cm (12 in) panicles. They appear in spring and early summer, and last for up to two months. They are followed by woody seed pods, about 5 cm (2.0 In) in diameter, which contain numerous flat, winged seeds. The blue jacaranda is cultivated for the sake of its large compound leaves, even in areas where it rarely blooms. These leaves are up to 45 cm (18 in) long and bi-pinnately compound, with leaflets little more than 1 cm (0.39 In) long. There is a white form available from nurseries. The unusually shaped, tough pods, which are 5.1 To 7.6 Cm (2 to 3 in) across, are often gathered, cleaned and used to decorate christmas trees and dried arrangements.
