There are many different kinds of onion cultivated as garden plants but the nodding wild onion has a special charm all of its own. In summer a cluster of white to pink flowers grows on a single scape emerging from a clump of grass like leaves and lasts about a month. Clumps increase steadily and are easily divided; plants readily reseed. Planted in groups this native of prairies, meadows, and open woods, is very effective in the border as well as in a wildflower garden.
