Canada garlic · Allium canadense
Also known as: meadow garlic; meadow leek; rose leek
Grow in full sun and fertile well-drained soil. It is best to grow in containers where garden soil is heavy clay and prone to saturation over winter. Increases rapidly and may become a nuisance, so best naturalised in a wild garden or meadow. See allium cultivation
