Gardeners' Notes:

Neutral Cretaceous On Jun 22, 2007, Cretaceous from El Sobrante, CA (Zone 9b) wrote:

Native to Mozambique and Cape Province, South Africa.

Stangeria eriopus grows in slightly acidic soils, which are usually sandy, but sometimes also in heavy clay soils. There are two distinct forms of this species: One grows in dry, open grassland habitat, the other in damp, dense forest. Average annual rainfall 30-39 inches.

It is listed on CITES Appendix I.

Positive palmbob On Oct 19, 2003, palmbob from Acton, CA (Zone 8b) wrote:

This cycad is native to eastern South Africa. It looks unlike any other cycad, looking more like a common plant with large, rounded, slightly soft leaves and no spines. It is the only plant in the genus. But it does reproduce by coning and has a caudex like other cycads (mostly underground, though). There are two forms- the open plains form (aka 'grassveldt form') with much stiffer, smaller leaves, and the forest form with large, long floppeier leaves.


This plant has been said to grow in the following regions:

Hayward, California
Mission Viejo, California
Thousand Oaks, California
