Albizia julibrissin (Mimosa) - Deciduous, rapidly growing tree that 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. Does best with high summer heat. With regular water, it grows fast; given skimpy moisture, it usually survives but grows slowly, looks yellowish. Excellent patio tree, despite fallen leaves, flowers, and pods. Most attractive as a multi stemmed tree.
