Description

Inject some dynamism into your borders with the dramatic architecture of these giant alliums. Allium ‘Giant Collection’ features huge umbels of purple, pink and white flowers. In May and June, these impressive globes float on tall stems above emerging grasses and perennials creating a magical display that will fill the gap between spring bulbs and the main summer show. Reliably perennial, they offer a head-turning performance for the minimum of effort!

Allium ‘Giant Collection’ comprises the following varieties:

  • Allium ‘Pinball Wizard’ – Thick stems rising up to 80cm support 4-inch, mid-purple globes. Height: 80cm (31in). Spread: 15cm (6in).
  • Allium stipitatum - Tall, slender stems carry tight globes with a flattened base composed of over 100 starry, lilac-pink flowers. Height: 1.5m (5ft). Spread: 15cm (6in).
  • Allium ‘Mount Everest’ – Large globes of more than 50 star-shaped white blooms. Height: 1.2m (4ft). Spread: 15cm (6in).
  • Allium ‘Magic’ - A cross between A. schubertii and A. atropurpureum, this unusual allium carries short-stemmed flowers close to the centre with longer-stemmed flowers bursting out around the circumference. Each head is up to 30cm across, composed of dark purple, starry flowers that bloom for a long period from early summer. Height: 50cm (20in). Spread: 15cm (6in).

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.
