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].

Growth—

Ephedra species are mainly temperate to subtropical plants, native to arid and semi-arid regions and are also found in seasonally dry habitats such as Mediterranean climates. They are often found at moderate to high elevations, especially when they occur in tropical regions. A plant of this species is growing at Hilliers Arboretum in Hampshire (hardiness zone 7). It has been there for many years so can be considered fully hardy. It is growing in the shade of Pinus mugo and seems to be thriving[PFAF]. Requires a well-drained loamy soil and a sunny position[2]. Plants are drought resistant once established and are also lime tolerant[3]. A dioecious species, 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[3]. 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[4]. Layering.
