'Lavender Bubbles' is a compact, late-blooming, hybrid selection of ornamental onion that features dark purple flowers and slightly twisted and curled foliage. Mature clumps will reach up to 1.25' tall and spread to fill a 2' area. The globular inflorescences can reach 3.5" wide and bloom in late summer atop 2' tall, upright scapes. The upright, strap-like, blue-green foliage twists slightly. The flowers are attractive to butterflies and other insect pollinators.
