There are only two howeas and they are both native to Lord Howe Island. The Kentia Palm is called Thatch Palm on the island because of its use in this way.

Kentia Palms were the iconic parlour palms of the Victorian era. They are very graceful plants with a single, smooth trunk and feathery fronds on long, smooth stalks. The flowers are small and fleshy and are borne on long arching spikes which grow up under the fronds and mature as small red fruit.

They were named after a father and son, Johann Reinhold Forster and Georg Forster, naturalists who sailed on Cook’s second voyage to the Pacific. The Forsters got the opportunity to sail with Cook after Joseph Banks withdrew from the expedition.

Growing conditions

Kentia palms are long lived plants. They tolerate low light, dry atmosphere and draughts – the perfect indoor plant!

Spraying with warm water may prevent the tips of the leaves from browning. They prefer a stable temperature and a minimum of 10°C. If the light is poor it is best not to have them in too warm an environment.

They should not be in bright sunlight. Kentia palms may be kept in the same pot for years as long as the potting mix contains some humus and is well drained.

Pest and disease problems

They are susceptible to Mealybugs, mites and Scale. Wolverton (see information sources) gives a recipe for a non-toxic spray:

2 teaspoons (10ml) vegetable oil
1/8 teaspoon (0.6ml) washing up liquid
230ml warm tap water
Shake vigorously in a spray bottle and spray the leaves.

Kentia Palm may succumb to Phytophthora in low light and very moist conditions.
