Allium triquetrum
Common Name: Three-Cornered Leek Family: Amaryllidaceae (The Amaryllis Family)

Allium triquetrum is an unusal ornamental and edible onion species producing loose umbels of drooping flowers numbering just 4-19 per head on three-sided stems. It has lush foliage. All parts of the plant are edible with a subtle leek or spring onion flavour. Few plants can offer the unique flower forms of ornamental onions. Every garden should have Alliums. Plant in multiples of 3, 5, 7 or more. Don't fret when foliage starts to die back just before flowering. It's normal. Just trim the leaves.
