Blue Eddy Allium
Blue Eddy Allium
A Dwarf Allium with Swirling Blue Foliage
Blue Eddy Allium (Allium senescens 'Blue Eddy') is a compact charmer grown for its tidy mound of slender, blue-gray leaves that swirl like eddies in a stream, topped in summer with rosy-pink flower globes that bees and butterflies love. Its small size and cool foliage make it perfect for the front of a border, rock gardens, edging, and containers. Tough, drought-tolerant, and deer-resistant, it's an easy, distinctive accent for sunny Eden Prairie, Plymouth, and Eagan gardens.

Blue Eddy thrives in full sun and average-to-lean, well-drained soil and asks for almost nothing once established. Not a fit for wet, shady spots, where the foliage flops and the bulb-like base can rot.
