Berberis darwinii is a species of barberry in the family Berberidaceae,[3] native to southern Chile and Argentina and naturalized elsewhere. English common names include 'Darwin's Barberry'. Vernacular names include michay, calafate, and quelung.[4]
It is an evergreen thorny shrub growing to 3–4 m tall, with dense branches from ground level. The leaves are small oval, 12–25 mm long and 5–12 mm 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.
B. darwinii was discovered (in Western science) in South America in 1835 by Charles Darwin during the voyage of the 'Beagle'; however, the berries of this species were consumed by prehistoric native peoples[5] in the Patagonian region over millennia. The species was one of many named in honour of Darwin.[6]
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.[7] The edible fruit is very acidic.
B. darwinii is regarded as an invasive plant pest in New Zealand[8] that escaped from gardens into indigenous plant communities via its bird-dispersed seeds.[9] It is considered a serious threat to indigenous ecosystems throughout New Zealand[10] and is listed on the National Pest Plant Accord. In Australia, the species is naturalised in the states of South Australia, Victoria, New South Wales and Tasmania.[11] The species has also become sparingly naturalized in the US states of California and Oregon.[12]
