The little nodding onion is a tremendously versatile and valuable garden addition. Nodding pink blooms (hence the name) attract a comical amount of bees, but are especially favored by large bumblebees. Humans also tend to enjoy the flavorful bulbs (they're even good raw!).
 
Individual plants are slender, so plant in groups to maximize visual impact. Over time, nodding onions will generate little colonies by reproducing clonally. They are nice "filler" plants around larger species. When they are in bloom, they are abuzz with little native bees. The nursery patch of nodding onion is always a center of pollinator activity.
 
Plant with sticky geranium, blanket flower, yarrow, small-flower penstemon or yellow beardtongue, Idaho fescue, and pussytoes for a pleasing range of colors and textures.
