Ramps are a wild onion native to the eastern US and Canada. They grow in the thick duff of the dappled shade in the understory of somehat open forest canopies. Ramps appreciate the moist summers of the east, so it's best to water them a bit in our dry summers. They multiply some, but don't spread very quickly.
The strap-like onion leaves appear very early in spring, and the little white clusters of flowers appear quite early as well. Each clump of leaves indicates the presence of a shallot-like bulb that is super delicious. They have a really unique flavor that is more tasty than your average onion. The leaves are edible as well.
