General tree description
Albizia julibrissin 'Rosea' is a small, spreading tree growing up to 8 metres tall. It has smooth, grey bark and large, light green bipinnate leaves. These are up to 45cm long and 25cm broad, divided into six to twelve pairs, each comprising twenty to thirty pairs of leaflets. The leaflets are oblong, up to 1.5cm long and 3mm broad. In late summer, lasting into autumn, there are clusters of bright pink fluffy flowers, followed by 15cm brown pods containing seeds.
Also known as Albizia julibrissin f. rosea, this tree is a form of Albizia julibrissin, of which it was considered a cultivar in the past. It is hardier and has deeper red flowers than the type, which needs maximum summer warmth to grow well.
