Nodding Onion (Allium cernuum)
We see three species of wild allium with some regularity on hikes in the Columbia Gorge and Cascades: acuminatum, the yet-unposted crenulatum, and this higher elevation variety found mainly in northern Oregon and Washington. All three are edible, and we’ve been known to snack on them occasionally. Just make sure they smell like onions before partaking–you’d hate to accidentally chow on a Death Camas.
In the picture below, what’s left of the onion-like skin of the bract that initially held the undeveloped blossoms, can be seen withering at the end of the green stem. The long green leaves are quick to turn brown, often before flowering occurs.
