Allium 'Bubble Bath ®'
Allium ‘Bubble Bath’
Description
Allium ‘Bubble Bath’ is a modern, free-flowering perennial Allium with a distinctive soft pink to lilac-pink flower colour. The cultivar stands out for its fresh, airy appearance, which is noticeably lighter and softer than that of many senescens-type Alliums.
The plant forms compact, uniform clumps with sturdy flower stems. At peak flowering, the spherical umbels are held closely together, creating a neat, even and well-structured display in the border. Like other contemporary selections, ‘Bubble Bath’ is reliable, vigorous and well suited for both private gardens and professional landscape plantings.
Thanks to its long flowering period and high nectar value, it is an excellent plant for pollinators. Easy to grow and low-maintenance in both cultivation and garden use.
