About
Heptapleurum actinophyllum (formerly Schefflera actinophylla) is a tree in the family Araliaceae. It is native to tropical rainforests and gallery forests in northern and northeastern Queensland coasts and the Northern Territory of Australia, as well as New Guinea and Java. Common names include Australian umbrella tree, Queensland umbrella tree, octopus tree and amate.
How to grow it
It is commonly grown in mild to warm climates as a decorative tree in larger gardens and, when mature, it has red spikes of flowers with up to 20 racemes which develop in summer or early autumn. Propagation is by seed or cuttings. It prefers well-drained soil and only needs occasional watering and feeding to thrive. It is, however, an aggressive plant and its roots can dominate surrounding soil. In some areas (e.g., Florida and Hawaii, USA), it is an invasive weed and therefore planting is highly unadvised.
With a minimum temperature of 13 °C (55 °F), juvenile specimens are grown in temperate regions as houseplants. This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Where it grows
The up to 1,000 flowers produced by the plant generate large amounts of nectar, attracting nectar-eating birds that pollinate them. The fruits are eaten by many birds and animals including musky rat-kangaroos, red-legged pademelons and spectacled flying foxes. Its leaves are a favourite food of the Bennett's tree-kangaroo.
