Allium

Position: full sun
Soil: fertile, well-drained soil
Rate of growth: average
Flower period: June 
Hardiness: fully hardyDense, rich-purple globes held high on erect stems above strap-like, pale green leaves appear in early summer. They look spectacular grouped in a pot, or in a sunny border, dotted in groups among ornamental grasses, or as part of a Mediterranean scheme. Alliums look best planted between medium-sized herbaceous plants, which help to mask the strap-like leaves, which fade by the time the flowers appear.
Garden care: Split and divide large clumps in autumn or spring.
