These ornamental onions will fit easily into most planting schemes and offer early summer colour as well as nectar for butterflies. This collection of 45 bulbs contains three very popular alliums, all of which can also be used for cutting.


In each collection you will receive the following:


  • 10 × Allium hollandicum 'Purple Sensation': Densely packed umbels of deep violet, star-shaped flowers with a striking architectural silhouette make this particularly good in gravel or prairie-style planting schemes. Grows to 1m.

  • 10 × Allium nigrum: Each creamy-white to pale lavender flower has a pronounced ovary at its heart, which looks a little like a green pearl, nestled in the centre. These form in flattish clusters that top the sturdy upright stems. Very pretty - and in big demand after its appearance in Cleve West's garden at Chelsea in 2012. Grows to 75cm.

  • 25 × Allium sphaerocephalon: Small, egg-shaped, claret-coloured flowerheads appear like drumsticks on tall, slender stems above strap-like, mid-green leaves in mid- to late summer. These diminutive claret flowers look great dotted amongst bushy perennials or ornamental grasses. They gently fade as summer comes to a close. Grows to 90cm.


  • Garden care: apart to enjoy the full effect of the flowers. Avoid excessive moisture from late summer when they become dormant. Over-large clumps can be lifted and divided in autumn or spring.

  • Planting tips:
    Plant bulbs 15cm deep and 15cm apart to enjoy the full effect of the flowers.
    • Pets: TOXIC if eaten; Humans: Ornamental bulbs - not to be eaten
