Cycas sexseminifera

A small cycad, often with a short or underground trunk, from the limestone karst hills of Guangxi and northern Vietnam. It suits growers who can give it hot, wet summers, a cool dry winter and a fast-draining, lime-rich medium.

Where it grows wild

Generalised from karst cycads of the region, since the source page gives no habitat detail: rocky limestone slopes and cliffs with scrub, often in crevices with little soil.

Recorded sites are low, around 260–280 m.
