Family: Rutaceae

Eight species of evergreen trees and shrubs native to New Guinea, Australia and New Caledonia, these often have a weeping habit and are mostly grown for their attractive shape. Dense clusters of small, ivory-coloured flowers appear amongst the long, lance-shaped, dark green leaves in spring.

Species

G. parviflora, wilga, from eastern and southern Australia, forms an attractive pyrami­dal shape, growing 5-6 m (16-20 ft) tall, and is valued for its aromatic hardwood. Its pendu­lous foliage is very graceful, the narrow, fra­grant leaves growing to 15 cm (6 in) long. Open clusters of small, whitish flowers appear pro­fusely in spring, followed by black seeds. It has been used as a fodder tree for sheep in drought conditions.

Cultivation

In frost-prone climates, grow in a cool to intermediate greenhouse or conserva­tory in soil-based potting compost. Provide maximum light and, as these plants are drought-tolerant, water only moderately in the growing season and sparingly in winter. Outdoors a dry spot in full sun is suitable. Propagate from seed sown in autumn.
