Firmiana
Family: Sterculiaceae
Common Name: Chinese Parasol Tree
This small genus of deciduous trees originates from Asia and Africa. Some are grown for their light timber but one species is especially known as an ornamental.
Species
F. simplex, from eastern Asia, grows to 20 m (65 ft). It has handsome, three- to five-lobed leaves, 25-30 cm (10-12 in) across, and unusual, papery fruits in autumn. The foliage turns yellow in autumn. The yellowish to greenish white flowers are borne in terminal sprays on the tree's thin stems.
Cultivation
These trees will do well in most normal soils but they must have some protecÂtion from wind. In areas prone to hard frosts, grow in a cool greenhouse or conservatory in large pots or tubs of soil-based potting compost. Can stand outside for the summer. Propagate from seed sown when ripe and germinate in a temperature of 13°C (55°F).
