Allium ramosum
$12.95
Essentially a non-nodding, central-U.S. version of the more easterly Allium cernuum, prairie onion produces spheres of lilac-pink flowers through much of summer. It's likes arid habitats, both in the wild and in cultivation, but is also fine in average soil.

Propagated from seed; deep 3.5-inch pots
