growing to 3 m long. The fine leaves are shiny, spear shaped, (pointed at
the tip), occurring in groups of three at intervals along the stem.
- Small white to pinkish flowers with six petals occur in late winter/early spring, (August to October), leading to fruits that are fleshy globular berries, orange-red when ripe. Produced from late October, fruits may be present at all times of year.
