Harvest calendar

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

Sharp, tart — mostly for jelly; barberry dried as a spice. Sold dried in Persian cooking as zereshk, used whole in rice dishes like zereshk polo.

Native range

Central and southern Europe east to the Caucasus and Turkey, in hedgerows, scrub and rough stony ground. ⚠ Naturalised in North America, where it is a regulated noxious weed in several states.

Status

Both wild and cultivated

Years to fruit

2–4 yrs

Growth speed

20–40 cm/year — medium.

Spacing

150 cm (59 in) apart — about 2.3 m² (24 sq ft) per plant

Leaf shape

Obovate, 2–5 cm long with finely spine-toothed margins, borne in rosettes above three-pronged spines — the branched spine separates it at a glance from the single-spined, untoothed Japanese barberry.

Root system

Shallow, spreading and suckering, with yellow inner bark and roots; forms thickets from root shoots over time.

Fruit description

Oblong bright red berries about 1 cm long in drooping clusters, sharply acid and rich in the alkaloid berberine; these are the zereshk dried for Persian rice dishes, and they make excellent jelly.

Propagation

Seed after 2–6 weeks cold stratification at about 4°C. Semi-ripe heel cuttings in late summer, or division of rooted suckers, both work. ⚠ It is the alternate host of wheat stem rust and propagating or planting it is prohibited in parts of North America — check before increasing it.

Pollination

Self-fertile — a lone bush crops well. The stamens are touch-sensitive, snapping inward when an insect probes the nectar glands at their base and dusting it with pollen; failing that, the anthers meet the stigma as the flower fades.
