ALBIZIA julibrissin f. rosea
Persian Silktree, Pink Siris, Silky Mimosa
A favorite of hummingbirds, silk tree is a multi-stemmed, spreading deciduous tree native from Iran to Japan. Its natural form rosea bears fragrant, fluffy, rich rose-pink flowerheads in summer and tan seed pods in fall. The ferny light green leaves emerge in late spring, and fold up at night. It includes the cultivar 'Ernest Wilson', a hardy selection that succeeds into USDA zone 5.
Silk tree thrives in most well-drained soils and flowers best in full sun. It is tolerant of drought, heat and saltspray and since it seeds so freely it is often regarded as an invasive species. It may be pruned back annual to grow it more as a multi-stemmed shrub. Its dome-like canopy is good for shading patios and spacious lawns.
