Soft lavender flower clusters are held on strong stems above a mound of glaucous blue green foliage. The wide, linear leaves have a slight twist. Compared to 'Millenium', 'Bubble Bath' has lighter purple flowers on larger 3" flower clusters. Compared with the bulb-type varieties like 'Globemaster', this type of Allium will have smaller, more numerous flower clusters, bloom in summer instead of spring, and have foliage that stays attractive through fall.
Alliums are charming plants for the rock or herb garden. When the foliage is bruised, it smells like onions since they are in the onion family. Butterflies and honeybees adore the flowers' sweet nectar but deer and rabbits steer clear of this perennial beauty.
