Albizia julibrissin f. rosea
Description: A spreading tree which is a smaller form of the species and produces rich pink fluffy clouds of flowers looking like silk threads in late summer - especially during a hot and sunny summer. The very feathery (bi-pinnate) leaves are produced on arching stems.
Uses: Best in hot situations on protected courtyards, as street trees or within built up areas where buildings reflect the heat. Otherwise grow in a large container and protect in winter.
Climate/Position: A sheltered site is essential and full sun required for any possibility of flowering.
Height/Spread: 4 x 3 metres.
Soil Requirements: Very free draining soil to avoid winter wet. Tolerant of drought.
Pruning: No pruning required unless formative pruning to shape a young plant.
Special Requirements: Though once Albizia was grown only as a conservatory plant, it is now possible to grow outdoors in the south of the UK but definitely requires a sheltered spot.
Additional Interest: Albizzia were introduced to Europe in the mid-18th century by Italian nobleman Filippo del Albizzi it is often confused with the mimosa (acacia). Many common names from its wide ranging native habitat add to confusion and include nemu which is a derivation of Japanese nemunoki or sleep tree referring to its leaves which fold up in the evening.
