What it's good for, and what it isn't

A thorny deciduous shrub with long, arching canes whose orange-red berries you know as goji: a single bush crops on its own without a pollination partner, and the berries ripen continuously from late summer to the first frosts. It is undemanding and copes with drought and with limy, poor soil, but it fruits best in full sun, tied to a support and cut back every year. It suckers strongly and the arching canes root where they touch the ground, so plant it behind a root barrier or in a large tub, dig out suckers regularly and do not let hanging shoots reach the soil.

Watch out for
In Central Europe it has long been naturalised and forms impenetrable thorny thickets by root suckers and bird-sown seed; it is on the official invasive list of a neighbouring country, so do not plant it near semi-natural land. By late summer the foliage is often covered in powdery mildew, the goji gall mite causes small bead-like galls on the leaves, and aphids also colonise it. Birds take the berries, and over-rich soil and uneven watering reduce the crop.
Considered invasive in a neighbouring country
It isn't listed here, but don't plant it near natural habitats, woodland or water, and don't leave the clippings outside the garden.
