Allium Bulbs

Allium bulbs are easy to grow and add colour to borders. Alliums are a great pollinator plant in various purples, blues, whites and yellows. They are perfect for adding architectural structure from May to June, and their seedheads add interest well into autumn.

Our top alliums for 2025

Alliums are a staple of the summer border and create show-stopper displays that return year after year. This year, we expect our most popular bulbs to sell out quickly, so grab your favourites before they disappear.

The most popular allium is Purple Sensation, and for good reason. Their striking silhouettes make them well-suited to gravel and prairie-style gardens. They have vibrant, densely packed, deep violet star-shaped flowers. The classic drumstick Allium sphaerocephalon is a fantastic late-flowering variety, blooming in July and August. Almost one metre high, they look stunning, planted en-masse and wave gently in the wind.

If you love the classic gigantic blooms, some really beautiful varieties exist. Allium Ambassador can grow up to 18cm across with densely packed flowers. If you love white flowers, Allium Mount Everest is a gigantic bloom that is a true show-stopper. Another giant is Allium giganteum, which lives up to its name at nearly two meters tall. For a large allium that is slightly different, try Allium cristophii with its 20cm wide spheres. The flowers are large stars less densely packed, giving them a galaxy-like appearance. Finally, Allium schubertii with its starburst effect. The flowerheads grow up to 30cm across and make beautiful dried flowers.
