Survives zone 7 through 9

Harvest calendar

Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

A California chaparral and woodland endemic, found from sea level to nearly 1,800 m. Red berries about 1 cm across, covered in stiff spines like a true gooseberry — eaten raw or cooked, or made into preserves.

Status

Wild

Years to fruit

Growth speed

20–40 cm/year — medium.

Spacing

120 cm (47 in) apart — about 1.4 m² (16 sq ft) per plant

Leaf shape

Small, rounded and 3–5 lobed with toothed margins, hairy to nearly hairless, on spiny stems — a true gooseberry, armed at each node.

Root system

Shallow and fibrous, spreading laterally close to the surface rather than going deep — so it resents drought and competes badly with turf, but transplants easily.

Fruit description

Round red berries about 1 cm across, thickly covered in stiff bristly spines — edible and pleasantly tart once the spines are rubbed or cooked off, though the armour makes picking slow work.

Propagation

Hardwood cuttings taken during dormancy in late autumn root readily and are the standard method. Seed needs about three months moist cold stratification at 4°C; layering the low branches also works.

Pollination

⚠ Cultivated currants and gooseberries are reliably self-fertile, but this is a wild species and the evidence differs: studies of wild Ribes (including R. nevadense and R. viscosissimum) found that essentially all seed-bearing fruit came from insect cross-pollination, with self-pollinated fruit selectively aborted. Plant two or more, and expect bees to matter — bee visitation measurably raises fruit set, fruit size and seed number.
