Family: Arecaceae
Common Name: Thatch Palm

Originating in the West Indies and the south-east of the United States, this small genus com­prises seven species of fan palms. Only one species, T. parviflora, is commonly cultivated. These palms are sensitive to frost, so where frosts occur, they should be grown as pot plants in a warm greenhouse or conservatory. Alterna­tively, they can be grown as house plants.

Species

T. morrisii, grows to about 10 m (33 ft). Being a small palm it is ideal for growing in containers. The young leaves of this species are densely covered with white scales on the under-sides. It is native to Florida and the West Indies, where it is known as the key palm.

T. parviflora, thatch palm or palmetto thatch, grows to about 10 m (33 ft), with a very narrow trunk. It is native to Jamaica, where it has been used as a source of thatch.

T. radiata is native to the Caribbean and Florida, where it is nor­mally found in coastal areas. It tolerates salt-laden winds and is ideal for planting in sub-tropical and tropical zones.

Cultivation

In the greenhouse or conservatory, grow in pots of soil-based potting compost. Ensure good light, but shade plants from direct sun. Outdoors these palms like well-drained soil and warm, sunny, humid conditions. Propagate from seed sown in the spring germi­nated at a temperature of 26°C (79°F).

Climate

Warmest parts of zone 10.
