Dioon mejiae

Description:
A small to medium sized cycad, to about 1m tall, with stiff, obliquely erect leaves to about 2m long. It has dark green leaves, that are flat in profile, and spineless leaflets (except the terminal leaflet, which can be quite sharp).

It is a very tropical looking Dioon, and similar in appearance, though usually much shorter than D. spinulosum. The latter develops many meters of trunk and tends to have a few spines on the leaflets even in adult plants.

It is usually a vigorous grower that holds a number of leaves in the crown.

Culture:
Sunny, well drained position, in the tropics or sub-tropics. Makes a great specimen plant in a relatively moist warm garden. Drought tolerant.
