While most Allium species are going summer dormant, this outstanding onion is in full flower. The 1-2" lavender-pink, globe-shaped blooms appear from June through August and remain ornamental even after they have faded. The 18-20" eye-catching, glossy-green, strap-like foliage is attractive all season. The flowers are reported to be sterile so unwanted offspring should not be a problem. It spreads by rhizomes to which tiny clusters of bulbs are attached.
