Lycium ruthenicum

Lycium ruthenicum, or Russian box thorn, belongs to the nightshade family, Solanaceae. It is a deciduous shrub that sheds its leaves each year. Plants reach about 6.6 feet (2 metres) in height. Its native range runs from eastern Türkiye to Mongolia and Pakistan. Kew places it in the temperate biome. It is not native to Britain or Ireland.

This shrub grows in harsh, open sites across its range. These include salt-rich deserts, sandy ground, and roadsides in western China. It also grows high in the inner Himalayas. Such habitats help explain its tolerance of dry and poor soils. In gardens, it needs a sunny site and cannot grow in shade. A sunny woodland edge is one suggested planting site.

The flowers carry both male and female organs, and bees pollinate them. The fruit is edible once fully ripe, either fresh or cooked. Do not treat this as proof that all parts are safe. Plants For A Future reports no known toxicity records for this species. Yet it urges caution with the leaves and unripe fruit. The nightshade family includes many poisonous plants, so that distinction matters.

Give this shrub soil that drains well rather than rich ground. Soil of modest fertility supports better flowering and fruiting. It accepts sandy, loamy, and clay soils if drainage is sound. It also grows in poor soil and soil with salt. Its pH range spans mildly acid, neutral, and mildly alkaline ground. It accepts dry or moist soil and withstands drought. It also tolerates exposed coastal conditions. Plants For A Future lists USDA hardiness zones 5–9.

Its wide root system makes it useful for holding loose ground. Plantings can help bind sandy soil and support banks. This gives the shrub a role beyond fruit growing. Growers can raise it from seed or take stem cuttings. They can also divide suckers in late winter. Pinching young shoot tips encourages a bushier shape. Seedlings need greenhouse protection through their first winter before planting out. A reported traditional use involves an ointment for eye disease in camels. This is a record of use, not proof of benefit.
