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 in the Patagonia
n region over millennia. The species was one of many named in honour of Darwin.
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.
B. darwinii is regarded as an invasive plant pest in New Zealand that escaped from gardens into indigenous plant communities via its bird-dispersed seeds. It is considered a serious threat to indigenous ecosystems throughout New Zealand and is listed on the National Pest Plant Accord
