Flowering in spring and early summer these plants combine well with other early-flowering perennials. Tall alliums provide vertical accents in sunny borders, while short ones are ideal near the front of the border. Buy and plant as bulbs to plant in autumn, or as potted plants in spring.
White, violet, purple or yellow star-shaped or bell-shaped flowers appear in late spring to early summer, either gathered tightly into a drumstick-like head or dangling in a looser cluster at the tops of stems.
Border alliums need free-draining soil in sun or light shade.
Very wet, heavy soils can cause bulbs to rot. They will not flower freely in shade.
Even after flowering the dried flower heads can look attractive in the garden or be used in flower arrangements.
All the information you’ll need to grow & care for alliums in your garden.
