Allium ‘Bubble Bath’ is a whimsical ornamental onion prized for its airy clusters of soft lavender-purple flowers that appear in late summer and early fall atop sturdy, upright stems. Before blooming, its glaucous blue-green foliage grows in a compact, attractive mound, adding season-long interest even before the blooms unfold. The clustered flowers resemble delicate bubbles floating above the foliage, creating visual contrast in perennial borders, containers, rock gardens, or pollinator plantings. A magnet for bees and butterflies yet generally ignored by deer and rabbits, this easy-care perennial brings texture, colour, and long-lasting appeal to sun-filled garden settings.
