Happy in full sun, your Allium would look fantastic grown in a border, cut flower, cottage or wildlife gardening scheme, as well as being a key statement shrub in low maintenance outdoor spaces. Your hardy bulb produces dense clumps of fresh green foliage, that add even more interest and contrast to its showy blooms. Plant in large groups for dramatic impact and watch it thrive to a height of 60cm, along with a spread of 10cm.

Growing Information

Alliums thrive in light sandy, well drained soil in full sun. Avoid planting in cold wet soils as they are prone to rot in these conditions. Plant alliums 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.

Live Plants

Suttons strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3.
