Plant description

This allium looks spectacular when grouped in a pot, or planted in a sunny border where they can be dotted in groups among ornamental grasses and other early summer flowers. Try to sandwich them between other herbaceous perennials, which will help to mask the strap-like leaves, as these tend to fade by the time the flowers appear.
