Discussion | Albizia julibrissin is commonly cultivated and is thought to be the hardiest of the Albizia species. It is especially attractive when flowering; staminal filaments are deep pink, grading to white at the base. Albizia julibrissin forma rosea (Carrière) Rehder is a dwarf, bushier plant with bright pink flowers. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Albizia procera is cultivated in southern Florida and is found outside cultivation in Miami-Dade County. In its native range, wood from the species is used for furniture and general construction. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
