Ephedra sinica is a Chinese native joint fir, found from Mongolia into China from 2,500'-5000' elevation, growing on sun-drenched, sandy mountain slopes. Ephedra sinica doesn't have leaves, instead it only produces rigid, narrow, evergreen blue-green branches making an ever-widening mat...most closely resembling a small horsetail on LSD. The highly medicinal Ephedra sinica, known in China as Ma Huang, is the source of Ephedrine, and we all know what's manufactured from that. Consuming a concoction from Ephedra sinica will soon have you resembling the aforementioned horsetail. This strange-looking conifer forms a great specimen in the hot, dry, rock garden.
