DescriptionEdit

It is a deciduous shrub growing to 2 m (7 ft) tall and broad.

The bark is dark brownish-grey with prominent paler brown lenticels.

The leaves are 2–7 cm (1–3 in) long and broad, palmately lobed with five lobes; when young in spring, they have a strong resinous scent.

The flowers are produced in early spring at the same time as the leaves emerge, on dangling racemes 3–7 cm (1–3 in) long of 5–30 flowers; each flower is 5–10 mm (0.20–0.39 in) in diameter, with five red or pink petals.

The fruit is a dark purple oval berry about 1 cm (0.5 in) long, edible but with an insipid taste.[6]

The Latin specific epithet sanguineum means “blood-red”[7]

CultivationEdit

Ribes sanguineum was introduced into cultivation by 19th century Scottish botanist David Douglas. It and its varieties and cultivars are popular garden shrubs, valued for their brightly colored and scented flowers in early spring, and birds and habitat support.

Numerous cultivars have been selected with flowers ranging from white to dark red. The following cultivars have gained the Royal Horticultural Society’s Award of Garden Merit:-[11]

  • ’Koja’[12]
  • White Icicle = ‘Ubric’[13]
