Physical Characteristics

An evergreen shrub growing to 2m. . It is in leaf all year. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). The plant not is self-fertile. We rate it 1/5 for edibility and 2/5 for medicinal use.

The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires dry or moist soil and can tolerate drought.

Habitats and Possible Locations

Cultivated Beds.

Edible Uses

Fruit Tea.

A tea is made from the branches[177].
Fruit - raw or cooked.

Medicinal Uses

Disclaimer

Diuretic Kidney Poultice Stomachic VD.

The dried and crushed stems are diuretic[238].An infusion has been used in the treatment of venereal disease, stomach complaints and kidney problems[257]. The pulverized or boiled stems were also applied externally as a poultice on syphilitic sores by some native North American Indians[213]. They can also be used as a poultice on other skin sores[257].
Unlike many members of the genus, this species is not very rich in the alkaloid ephedrine and so is not used in the treatment of asthma[238].

Other Uses

None known

Cultivation details

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors at least in the milder parts of this country. It 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[270].The following notes are based on the general needs of the genus.
Requires a well-drained loamy soil and a sunny position[1, 11]. Established plants are drought resistant and are also lime tolerant[200].
Dioecious, male and female plants must be grown in fruit and seed are required.

Propagation

Seed - best sown as soon as it is ripe in the autumn in a greenhouse[200]. It can also be sown in spring in a greenhouse in a sandy compost[K]. 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[K].
Division in spring or autumn[238].
Layering.

A nice book to read though it is difficult to look up individual plants since the book is divided into separate sections dealing with the different medicinal uses plus a section on edible plants. Common names are used instead of botanical.
