So cute! Blue Eddy Ornamental Onion is an adorable Spirit that you’ll want to show off at the front of the border. This charmer features narrow blue-green leaves that make a cool spiral pattern like an “eddy” of water. It’s pretty enough to use purely as a foliage plant, but Blue Eddy is more than that. In late summer, spherical flowerheads like lavender-pink pompoms rise above the swirly leaves. Bees, butterflies, and other pollinators adore the perky blooms. Plant Blue Eddy in drifts for greatest impact and pollinator appeal. You’ll find it easy to grow in any sunny, well-drained site.

The Story

Onions belong to a genus (Allium) that includes familiar edibles like garlic, chives, shallots, and so much more. There are around 850 species of Alliums in the world, nearly all of them native to the Northern Hemisphere. Blue Eddy is a selection of German Garlic, an Ornamental Onion from a vast region ranging from Western Europe to Korea. This variety was bred by Mark “The Onion Man” McDonough of Pepperell, Massachusetts. McDonough is an architect by trade and an amateur gardener on the side with a passion for ornamental onions. He introduced Blue Eddy in 2004.

The Details

Grow Blue Eddy Ornamental Onion in a container with other low-water Spirits to create a festive, low-maintenance display. Put dark-foliaged plants behind it to make the twisted blue foliage and pinkish flowers really pop.

How to Grow

Plant Blue Eddy Ornamental Onion in a site in all-day sun; afternoon shade may be a good idea in very hot climates. Blue Eddy grows best in light (sandy), free-draining soils. It has average to low water needs, withstanding periods of drought once established. Most border situations suit it well, and it is at home in the rock garden, too. To use the flowers in arrangements, cut them as soon as they open, and they’ll last a long time in water. Diseases and insect pests are rarely a problem with this carefree Spirit; deer and rabbits avoid the aromatic foliage as well.
