'Blue Eddy' was named for the way its blue-gray to gray-green whorls of foliage resemble swirling eddies of water. Easily grown in average, dry to medium moisture, well-drained soil in full sun to part shade. Best in full sun, but appreciates some light afternoon shade in hot summer climates. Tolerates a wide range of soils. Tolerates drought. Although this allium is a true bulb (albeit weakly developed) on a rhizome, it forms a clump which can be lifted and divided somewhat easily in either spring or autumn. It will spread in the landscape by short fleshy rhizomes and by self-seeding. Deadheading spent flowers before seed sets not only helps control unwanted spread but also helps build a stronger bloom for the following year.
