Albizia julibrissin

Silk Tree, Mimosa
Fabaceae (Leguminosae)
Deciduous, Trees

Native to Asia, ranging from Iran to Japan. This open grower, sometimes called silk tree, rapidly reaches 40 ft. tall, with a canopy spreading to as much as twice the tree’s height. Ferny, pale yellowish green leaves are light sensitive and fold at night. The fluffy pink, summertime flowers look like pincushions or powder-puffs and appear even on young plants. A. j. rosea has richer pink flowers and is considered hardier. ‘Boubri’ (‘Ombrella’) bears hot pink blooms. ‘Summer Chocolate’ has rich burgundy foliage.

Mimosa does best with high summer heat; it’s a best seller in Southern California’s inland valleys. In Zones 4 and 5, choose the warmest locations possible. With regular water, it grows fast; given skimpy moisture, it usually survives but grows slowly, looks yellowish. Flat-topped, spreading canopy makes this a good patio tree, despite fallen leaves, flowers, and pods. Beautiful when viewed from above. Most attractive as a multistemmed tree. Tough to get started as a high-headed tree: it must be staked and trained (rub out any buds too low on the trunk with your thumb). Start with trees planted from containers established at least 1 year.
