Safety & Hazards

Many species in this genus contain phenylethylamine alkaloids (e.g. ephedrine, pseudoephedrine). These compounds have stimulant properties and are effective medications in the treatment of a number of conditions. However, they do also have potential side effects and are contraindicated in a number of conditions including anxiety, anorexia, bulimia, diabetes, glaucoma, hypertension, thyrotoxicosis[1].

Cultivation Details

Growth—

Most Ephedra species are native to warm, dry, inhospitable regions, frequently found on stony slopes and gravel terraces, often on limestone[2]. Ephedra americana is found mainly in the subtropical regions of the Andes and is generally not very frost tolerant.. Requires a porous, freely-draining soil in a sunny position[2]. Grows well in dry soils and are very drought tolerant once established[2]. A dioecious plant, both male and female forms need to be grown if fruit and seed are required. Plants require a good summer in order to fully ripen their wood - this will encourage good flowering and fruiting the following summer.

Propagation

Seed - best sown as soon as it is ripe in the autumn in a greenhouse[2]. It can also be sown in spring in a greenhouse in a sandy compost[PFAF]. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow them on for at least their first winter in a greenhouse. Plant out in the spring or early summer after the last expected frosts and give some protection in their first winter[PFAF]. Division in spring or autumn[3]. Layering.
