When supported, the plant can grow up to in height. The compound leaves with 5 to 9 leaflets are dark green on the upper surface and a lighter green beneath, with glabrous,
terete or angular branches. The terminal
leaflet is noticeably larger than the other leaflets.
Inflorescence The species is
heterostylous, meaning that a few distinct flower morphs (forms) are available, though each plant bears only one morph. In late winter and early spring it produces an abundance of reddish-pink flower buds, followed by fragrant five-petalled starry white flowers which are about 2 cm ( inch) in diameter. The
bracts are
subulate (tapering to a point), 1-6 mm. Each flower is carried by a
pedicel (single stalk) of 0.5 - 2.5cm ( - 1 inch) The
calyx forms a 1-2 mm tube terminating in 5 triangular or subulate-linear lobes, only 2 mm long, and a
corolla, white, with a red underside and red buttons. The fruit is a black, globular berry. == Distribution and habitat ==
