A. cowanii is a 1823 heirloom prized for its sprays of glistening white floral umbels. Each 2”-wide umbel is comprised of dozens of white florets adorned with ivory-green anthers and pale green eyes (ovaries). Long-lasting, it is ideal in full sun to partial shade, in densely planted borders and rock gardens, forced pots and bouquets. Bulb size: 5 cm/up. May. 16” to 24”. HZ: 6-9. (The size, or circumference, of Allium is measured around the widest part of the flower. From left to right, the flower would be about 1”, while the circumference around the flower would be 2”.) 

The Flowering Onions are rabbit-, rodent- and deer-resistant, and are seldom affected by disease. Adored by bees, butterflies and pollinators, Allium extend the spring flowering season, and are valuable cut and dried flowers.

Allium require rich, well-draining and neutral pH soil and can benefit from a summer dry period. All Allium must be planted outdoors in the fall after the soil has cooled down to around 55 degrees F (normally after two weeks of night time temperatures hovering around 40 degrees F). Plant 4" deep and 3" to 4" apart.
1. In the Fall, choose a spot that is somewhat sunny and has nicely well-draining soil.
