Noted for its striking dark foliage, award-winning Albizia julibrissin 'Summer Chocolate' (Silk Tree) is a large shrub or small deciduous tree of vase-shaped habit with an umbrella canopy of large, fern-like, deep burgundy leaves. Emerging bronze-green, the leaves mature to purple as the season progresses and retain that color into fall, even in hot and humid conditions. Fluffy, pink and white, pincushion-like flowers adorned with prominent stamens, open in early summer and cover the tree. Fragrant, the blossoms are attractive to bees and butterflies. They are followed by flat bean-like seed pods, 7 in. long (17 cm), which persist into winter. A colorful and exotic-looking landscape tree that is most attractive as a multi-stemmed tree.
