Allium Ostara

Alliums are among the most breathtakingly beautiful plants for the landscape, and we are proud to introduce our newest variety, Ostara. A captivating cross between Allium Karativiense and Allium atropurpureum, Ostara sports large 4-6" flower heads of dark purple that top 16" stems—a perfect height for borders, patio pots and cut flowers. While the blooms appear from May to June, the foliage remains attractive much longer than most other alliums. A popular variety for attracting pollinators to the garden. Cannot be shipped to ID, WA.
