Richwood has a large festival every year for Allium tricoccum which they call what?
Allium tricoccum Allium tricoccum (commonly known as ramp, ramps, spring onion, ramson, wild leek, wood leek, and wild garlic) is a North American species of wild onion widespread across eastern Canada and the eastern United States. Many of the English names are also used for other "Allium" species, particularly the similar "Allium ursinum" which is native to Europe and Asia.
Allium constrictum Allium constrictum, the Grand Coulee Onion, is a plant species endemic to the US State of Washington. It is known from only three counties in the east-central part of the state: Douglas, Grant, and Lincoln. It grows on dry, sandy soils at elevations of 300-500 m.
