Allium 'Purple Sensation' is certainly sensational in its popularity among gardeners as well as its absolutely striking good looks, and you’ll be thrilled to have it. At the end of a fairly short stalk, 100 or more lavender purple stars shoot out in a circle of superb symmetry and seemingly painted-on colour. Any great artist would be proud to have designed these flowers, and a cluster is a breath-taking sight. Plant several Allium 'Purple Sensation' bulbs (commonly known as Dutch garlic) close together and see for yourself why this is one of the trendiest plant species to have in your garden. They also smell divine and butterflies flock to them. Just fabulous!
The long-lasting, sweetly scented blooms of Allium hollandicum 'Purple Sensation' last well in the vase, and even the spent flowers look striking with their structured flower stems precisely arranged in their spherical pattern. All in all, it’s a gorgeous plant, with a sculptural yet airy appearance, and it’s pleasant to see it finally winning gardener’s hearts as it deserves.

Plant profile
Plant calendar
Choose full sun or partial shade. Improve heavy soil with organic matter and horticultural grit. For containers, use peat-free multipurpose compost with good drainage.
Plant bulbs pointed side upwards, two to three times their own height deep. A slightly flattened side is perfectly normal and nothing to worry about.
Space small bulbs around 5cm apart. Larger bulbs need more room, generally around twice their own width apart, so their foliage and flowers can develop freely.
Water after planting if the soil is dry, then only when needed. After flowering, allow the foliage to die back naturally. Decorative seedheads can remain in place.
