Contents

Distribution

Allium triquetrum is native to south-western Europe, north-western Africa, Madeira and the Canary Islands, where it grows in meadows, woodland clearings, on river banks and roadside verges from sea level to an altitude of 850 metres (2,790 ft).[1] It has also been introduced to the British Isles, Turkey, Australia, North America and South America.[1]

Description

Allium triquetrum produces stems 17–59 centimetres (7–23 in) tall, which are concavely triangular in cross-section. Each stem produces an inflorescence of 4–19 flowers in January–May in the species' native environment.[1] The tepals are 10–18 millimetres (0.4–0.7 in) long and white, but with a "strong green line".[2] Each plant has 2–3 narrow, linear leaves, each up to 15 cm (6 in) long.[1]
