Pink Silk Floss Tree

Pink silk floss tree is a broadleaf tree with an often-swollen trunk that can develop large conical prickles. Its showy flowers combine pale-pink to rose petals with a pale center, and mature seed capsules open to release silky white fibers. ## Form and Seasonal Interest Oregon State University reports that flowering may occur in summer or fall, sometimes after leaves drop. The species can grow to about 60 feet high and 30 feet wide in that profile; UF/IFAS gives broader mature ranges of 35–50 feet high and 40–55 feet across. These differences show why a large, open planting site is important. The trunk and surface roots can occupy space close to the tree. ## Siting and Growing Plant in full sun for best flowering and in soil with good drainage. UF/IFAS describes the tree as drought tolerant and hardy in USDA Zones 10A–11; Oregon State reports hardiness to Zone 9, so local winter conditions matter. Young plants need protection from cold, and the species is better suited to warm climates. ## Maintenance Prune young trees to establish a strong central leader and well-spaced main branches. Keep the mature root area away from pavement and narrow planting strips.
