Albizia lebbeck
Lebbeck Tree - Siris 
 
A fast growing, deciduous, small tree known mainly as mimosa or lebbeck tree. A smooth trunk is accented by small leafed foliage and arching branches. Delicate small flowers are white and bloom in profusion and look like fluffy silk powder puffs followed by pods that can be heard rattling in the wind.  Loves full sun but will tolerate partial shade. Somewhat drought tolerant. Zones 9 as an outdoor standard. Makes a perfect landscape accent plant as well as a bonsai specimen.
