Alliums never fail to impress. They come back year after year, flower over a long period, provide structural interest and will easily fit into any border scheme. No wonder then they are always in big demand by the top designers.


In each collection you will receive the following:

  • 25 × Allium neapolitanum Cowanii Group: Open clusters of pure white flowers appear in late spring or early summer, creating a soft, lacy effect. The flowers last for ages after being cut and the bees will find them very attractive, so try to plant them in large numbers. In smaller gardens, they look great in pots where they can sit on a sunny patio. Grows to 40cm tall.

  • 25 × Allium sphaerocephalon: The small, egg-shaped, claret-coloured flowerheads appear like drumsticks on tall slender stems above strap-like, mid-green leaves in mid- to late summer. Planted en masse in a border in full sun, these diminutive claret flowers look great emerging from a screen of foliage, or against a backdrop of ornamental grasses. They gently fade as summer comes to a close. Grows to 90cm tall.

  • 25 × Allium unifolium: The flowers on this allium are quite papery, which means they last longer then many of the other varieties. In spring the first sign of growth is the appearance of the strappy foliage, which has usually died off by the time the flowers appear in late spring. The pinky purple bell-shaped flowers emerge in clusters of up to 20 at a time on top of single stems. After they have flowered the papery seed heads make a beautiful rattle as they blow in the breeze. The Royal Horticultural Society have also justifiably awarded it an Award of Garden Merit for its garden worthiness. Grows to 30cm tall.


  • Garden care: Avoid excessive moisture from late summer when they become dormant. Over-large clumps can be lifted and divided in autumn or spring.
    • Pets: TOXIC if eaten; Humans: Ornamental bulbs - not to be eaten
