Description

A dense, attractive shrub or small tree with dark green leaves 3-10m high, sometimes scrambling. The common names are "crossberry" and "four-corner." Its simple leaves are shiny, deep green and slightly fleshy, about 5-7cm long with small rounded teeth. The sepals and petals form unusual double star-shaped flowers, purple, mauve, pink or rarely white, 1.5-3cm across. Flower time is summer, followed by four-lobed fruits (drupes). These shiny reddish-brown berry-like fruits remain on the tree after maturity and attract fruit-eating birds.

The root system is not aggressive and can therefore be planted near buildings and paving, and it is very good at attracting butterflies and birds to the garden. The crossberry is best propagated from seed, although even then it can be erratic, as usually the seed needs to pass through the gut of a
