Our "Bloom or Bust" Promise

Bees and butterflies think it's sensational too! Pollinators absolutely flock to these vibrant purple spheres making them a lively hub of garden activity.

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.

Where to Plant:

Choose a location that receives at least six hours of direct sunlight per day. Well-drained soil is essential, as these large bulbs will rot in soggy ground. They are perfect for adding height and structure to the back or middle of perennial borders and make stunning, long-lasting cut flowers.

How to Plant:

In the autumn, plant each bulb with the pointed tip facing upwards, about 15-20cm (6-8 inches) deep. This depth is crucial to help support their tall, heavy flower heads. Space them at least 20-30cm (8-12 inches) apart to give them room. For a powerful visual statement, plant in bold drifts of five or more bulbs. Water them once after planting to help settle the soil.

Aftercare:

Once the impressive flower globes fade, allow the foliage to die back and turn yellow naturally. Do not cut it down while it is still green. This is the most important step for ensuring a repeat performance, as it allows the plant to store energy in the bulb for next year's bloom. The dried seed heads can be left for extended structural interest or removed by snipping the stalk at the base.

I ordered the mixed hyacinth collection and the scent in my garden this April was absolutely heavenly. Every single bulb produced a strong, beautiful flower and the colours were stunning together. A fantastic purchase, I'll be back for more next year!
