Uses

Toxic parts

Although no records of toxicity have been seen for this species, it does belong to a family that contains many poisonous plants. Some caution should be applied, especially towards leaves or unripe fruits, though ripe fruits are almost certainly edible.

Edible uses

Notes

Fruit - raw or cooked[1]. It is much sought after in the wild[2]. Only the fully ripe fruits should be eaten[K].

Unknown use

Material uses

Plants have an extensive root system and can be planted to stabilize banks[3].
There are no material uses listed for Lycium torreyi.

Medicinal uses(Warning!)

A poultice of the heated root has been applied to the jaw to bring relief from toothache[1].

The plant has been used as a treatment for chickenpox[1].

The fruit of many members of this genus is a very rich source of vitamins and minerals, especially in vitamins A, C and E, flavanoids and other bio-active compounds. It is also a fairly good source of essential fatty acids, which is fairly unusual for a fruit. It is being investigated as a food that is capable of reducing the incidence of cancer and also as a means of halting or reversing the growth of cancers[4].

Propagation

Seed - sow early spring in a greenhouse. Germination is usually good and fairly quick. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first winter. Plant out in late spring or early summer. Pinch out the shoot tips of the young plants in order to encourage bushy growth[5].

Cuttings of half-ripe wood, 5 - 10cm with a heel if possible, July/August in individual pots in a frame. Good percentage[5]. Cuttings of mature wood of the current season's growth, autumn to late winter in a cold frame. High percentage[5][3]. Division of suckers in late winter. Very easy, the suckers can be planted out direct into their permanent positions.

Cultivation

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 might succeed outdoors in the mildest areas of this country. The following notes are based on the general needs of the genus. Does not require a rich soil, flowering and fruiting better in a well-drained soil of moderate quality[6]. Succeeds in impoverished soils[3]. Requires a sunny position[3]. Tolerates maritime exposure[3].
