Mimosa trees are a member of the Fabaceae family and are a popular ornamental tree in the home landscape. Also known as silk trees and Albizia silk trees, these beauties have a lovely feathery habit with wispy pink to rose aromatic flowers. Ideal for USDA planting zones 6 through 9, this tree provides light shade and adds a lovely burst of color amongst other deciduous or evergreen trees, or when used as a specimen. The fringed foliage ranges from bright green to chocolate brown, depending on the variety.
