Allium senescens ssp. montanum var. glaucum


This Allium species grows in a circular clump that expands as plants age. The curly leaves form a wonderful spiral effect. It is a slower-growing plant that will take a couple of years to develop on a green roof; very much worth the wait. The flowers are lower and larger than other Alliums and make a nice contrast against the slightly bluish-green foliage. Flowers attract butterflies, bees, and other pollinators. Foliage remains throughout most of the winter months, but, is not as lush in autumn as in the spring and summer. Brown seed heads can remain upright throughout the coldest temperatures of winter.

Sold as bare root bulbs. Available in plugs as a custom order. Please contact the office for lead times.
