Culture

Licuala dasyantha (Now Lanonia dasyantha), incorrectly known as Licuala radula before, is a vulverable species now listed on the endangered and protected list. It was first found in a limestone mountain as a small, clumping palmate palm up to 2m tall, with attractive mottled leaves,though not as highly developed as Mapu. It is monoecious (having separate male and female reproductive units on the same plant) whose seeds are mature in November. Different from other tropical Licuala, Licuala dasyantha is probably the most cold hardy in its genus and more interesting is that it has striking yellow dots and rings on the leaves making them quite cute and beautiful.. Say in 2002, the 1 year old seedling and adult palms did get notice any damage after 2 continuous raining days as low as -2C(28.4F) in Guilin City, Guangxi Province where the lowest temerpature goes down to -5C.

Comments and Curiosities

Previous name Licuala dasyantha.

This little known small palm is native to rainforests in northern Vietnam between 100 and 1000 m and reaches just over the border into southern China (Guangxi). It forms an underground or briefly erect trunk to 1.5 m tall that holds a dense crown of fairly large, beautifully mottled, light and dark green leaves to 1 m in diameter with a few wide segments, similar to the magnificent L. mattanensis Mapu. While not as spectacular as the ultra-tropical Mapu, it has the advantage of being much more tolerant of cool conditions and will actually grow successfully not only in tropical but also in warm temperate climates, where it appreciates a protected spot in filtered light.
