Rosy-purple spheres perch atop straight leafless stems to introduce a playful touch to any sunny garden. Flowers rise above a mound of blue-tinged foliage blades. Onion-scented foliage and flowers keep deer and rabbits at bay.

Easy care, Alliums multiply naturally and can be left undisturbed in the same area for years. Butterflies adore ornamental onion! Allium Serendipity, with its interesting flower shape, creates texture and depth. It adds a perky, colorful focus to your late summer garden. You will love this low maintenance, dependable garden workhorse, and pollinators will too!
