Description
Single stemmed or branched (usually at the base). The leaves are large and strap-shaped in rosettes at the tips of the stem/s. The leaves are leathery, shiny, and dark green, with whitish margins. These plants may grow up to 4 m tall. The flowers are produced on a much branched flowering head. The flowers are silvery-white and described as sweetly or strongly scented. The two-lobed berry-like fruit ripen to a reddish-orange colour.
Ecological Significance
The flowers open from late afternoon to early morning and attract night-active pollinator moths. Birds eat the fruit; helping to remove the orange pulp which contains a growth inhibitor that otherwise slows germination of the seeds. Snails and the larvae of the Bush Night Fighter butterfly, Artitropa erinnys, feed on the leaves. Birds and mice nest among the leaves of these plants.
