Nursery contributed plant descriptions

Allium triquetrum is an unusual ornamental and edible onion species producing loose umbels of drooping flowers numbering 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. Tolerant of shade. 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.

A tall, late Winter, early Spring bloomer with white, pendulous, Lily like, almost Galanthus like flowers with green stripes on 12-18" stems . A very vigorous grower to say the least.
