Thompson & Morgan Allium Mixed Collection – 200 Bulbs

Alliums are prized by gardeners for their stiff, upright habit that lends structure and colour to early summer borders. This superb collection brings together four 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 – An understated allium with unusual oval shaped, purple green flower heads, that associates beautifully with swaying grasses. Height: 60cm (24″). Spread: 8cm (3″).Allium moly – Dense clusters of star-shaped, golden yellow flowers from late spring. Height: 15cm (6″). Spread: 5cm (2″).Allium ‘Graceful Beauty’ – Effortlessly tasteful – its large, starry blooms forming spherical flower heads in spring. Each gleaming white flower is blushed with palest pink providing a lovely contrast with its violet stamens. Height: 30cm (12″). Spread: 10cm (4″).Allium ‘Purple Sensation’ – Globes of starry purple flowers that measure up to 8cm (3″) across. Height: 90cm (36″). Spread: 10cm (4″).Growing InformationAlliums 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.
