Pisonia umbellifera (syn. P. brnnoniana, Heimerliodendron brnnonianum)

This plant is native to New Zealand and to islands of the Pacific and Indian Oceans, where it grows to a height of 6 m (20 ft). There is no need to worry about its becoming too tall, for it can be easily pruned and kept to a reasonable size without any harm to the plant. It is grown for its ornamental foliage. The opposite leaves, up to 40 cm (16 in) long, are leathery and coloured dark green with prominent, yellowish or creamy-white patches. The inconspicuous greenish flowers are hardly ever produced by potted plants.

It requires a light position but it should be protected against direct sun. It thrives at high temperatures. Do not allow the temperature to fall below 18°C (64°F) in winter. A loam and peat compost is best. Water regularly to keep the compost constantly moist. Feed the plants from spring to autumn with a stronger concentration of liquid fertilizer every one or two weeks. This is particularly important for plants that have not been repotted. Propagate by tip cuttings, which require a temperature of at least 25° C (77° F) to root.
