Description

Alliums are prized by gardeners for their stiff, upright habit that lends structure and colour to early summer borders. This superb collection brings together 4 unusual species which are particularly well suited to gravel gardens and rockeries. When planted in dense groups they create an eye-catching display that bridges the gap between spring bulbs and summer perennials. Like all Alliums, they are easy to grow and virtually maintenance free once established.

Allium Collection comprises:

  • Allium sphaerocephalon - Unusual oval shaped, purple-green flower heads. Height: 90cm (36"). Spread: 8cm (3").
  • Allium moly - Dense clusters of star-shaped, golden yellow flowers from late spring. Height: 15cm (6"). Spread: 5cm (2").
  • Allium neapolitanum - Loose heads of starry white blooms. Height: 40cm (16"). Spread: 10cm (4")
  • Allium ostrowskianum - Delicate pink, bell-shaped blooms in early summer. Height: 20cm (8"). Spread: 5cm (2").

Show Codes

200 allium bulbs - 50 of each variety (KB2096)

100 allium bulbs - 25 of each variety (KB2095)

How to Grow
Alliums thrive in light sandy, well drained soil in full sun. Avoid planting in cold wet soils as the bulbs are prone to rot in these conditions. Plant allium bulbs at a depth of 10cm (4") and a distance of 10cm (4") apart. A slow release fertilizer can be added to poor soils at the time of planting to improve fertility. When growing alliums, plant them where the leaves of other plants will cover the base of their stems. This will hide the old foliage which dies back before flowering begins.
More Info
Alliums require little maintenance. Leave stems of faded allium flowers intact to enjoy their spectacular seedheads in autumn. Divide overcrowded clumps of alliums after flowering. Caution: irritant to skin and eyes.
