Jeg vil foreslå dig at købe nogle frø, for derefter at smide dem i noget muldjord og vande dem... Det er som regelt sådan man sår botaniske vækster.

Min egen erfaring med Ephedra Nevadensis, er at den faktisk ikke behøver særligt meget pleje.

Cultivation and Propagation: Ephedra should be planted in dry locations. It thrives in ordinary loamy soil and does very well in a loose rocky soil with full sun and little water. It is most often propagated by division of the clumps in spring, and seeds sown in a light sandy soil in early spring. It may also be propagated by layers and suckers. It makes an excellent ground cover on rocky slopes.
Harvesting: The tops of the branches may be picked and dried at any time as long as the plant is not denuded or the branches cut back past the viable buds.
