Ephedra trifurca
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].Many species in this genus contain phenylethylamine alkaloids (e.g. ephedrine, pseudoephedrine).

Cultivation Details
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 Requires a well-drained loamy soil and a sunny position[2, 3]. Established plants are drought resistant and are also lime tolerant[4]. 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. Ephedra trifurce hybridises in the wild with other members of the genus. In particular, it hybridises with E. torreyana to form E . × intermixta. This hybrid occurs in a small area of southwestern New Mexico (near Engle, Sierra County) within the zone of sympatry of the two parental species; it may be fertile (mature seeds are formed). It is intermediate in most characters but can be identified by its combination of the spinelike terminal buds of E . trifurca and the scabrous, light yellow seeds of E . torreyana[5].
Propagation
Seed - best sown as soon as it is ripe in the autumn in a greenhouse[4]. 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[6]. Layering.
