Jacob’s coat (Acalypha wilkesiana)
Description
Acalypha wilkesiana, common names copperleaf and Jacob’s coat, is an evergreen shrub growing to 3 metres (9.8 ft) high and 2 metres (6 ft 7 in) across. It has a closely arranged crown, with an erect stem and many branches. Both the branches and the leaves are covered in fine hairs The leaves, which may be flat or crinkled, are large and broad with teeth around the edge. They can be 10–20 centimetres (3.9–7.9 in) long and 15 centimetres (5.9 in) wide. The leaves are coppery green with red splashes, giving them a mottled appearance. Separate male and female flowers appear on the same plant. The male flowers are in long spikes which hang downwards while the female flowers are in short spikes. The latter do not show up easily as they are often hidden among the leaves. The flower stalks are 10–20 cm long. A. wilkesiana is a tropical and subtropical plant which grows naturally in Vanuatu and occurs in the Pacific Islands. It prefers light well drained soil and is suited to a protected shady position. It can be damaged by both drought and frost. It needs a minimum temperature above 10 °C (50 °F). It is best suited to hardiness zones 9-12. In South Florida and tropical America, copperleaf is a popular outdoor plant that provides colour throughout the year. It is used in mixed hedges and shrub borders and as a specimen shrub. Elsewhere copperleaf is grown as an annual where its spectacular foliage replaces flowers from late summer until frost. Copperleaf is also grown indoors as a container plant. However, it must be maintained in a warm, humid, bright environment. This plant has gained the Royal Horticultural Society’s Award of Garden Merit.
