Darwin's Barberry

Berberis darwinii has dense branches from ground level. The leaves are small oval, 12–25 mm (0.47–0.98 in) long and 5–12 mm (0.20–0.47 in) broad, with a spiny margin; they are borne in clusters of 2–5 together, subtended by a three-branched spine 2–4 mm long. The flowers are orange, 4–5 mm long, produced in dense racemes 2–7 cm long in spring. The fruit is a small purple-black berry 4–7 mm diameter, ripening in summer. Berberis darwinii was first described in 1835 by Charles Darwin during the voyage of the Beagle. It was one of many named in honour of Darwin. The berries of this species are known to have been consumed by prehistoric native peoples in the Patagonian region over millennia. It is a popular garden and hedging shrub in the British Isles. The Royal Horticultural Society has given the species its Award of Garden Merit. The edible fruit is very acidic.
