Distribution and Habitat
Endemic to Taiwan, where it is
restricted to 2 localities in the county of Taitung in the south east
of the island. This species grows in exposed sites on rocky ridges,
ravines and steep rocky slopes in shallow, stony skeletal soils and
gravels at 300 - 950 m altitude. The climate is warm to hot and humid
for much of the year.
The species is reduced to rarity in Taiwan as the result
of clearing and over collecting, and is protected in a 300 ha nature
reserve north west of Taitung City. It can be immediately distinguished
from Cycas revoluta by its longer leaves with flat leaflets.
Suited to tropical, subtropical and temperate
regions. This species is reputedly cold-hardy, surviving down to
temperatures as low as -9 C. An attractive fast growing species which
has become extremely popular and is now widely cultivated. Flushes of
new leaves can be an impressive and attractive feature. It is best
planted in full sun, requires unimpeded drainage and responds to
watering, mulching and fertilising.
From seed and offsets.
