Wild chives is the exact same species that you grow in your garden. I’m not sure why they call them “Wild”. Maybe it has something to do with their character, e.g. Wild Chives and Soybean Soup (haven’t seen it, tell me if you like it).
Chives are one of the Allium plants, which include onions, garlic, and leek. They all can be used for cooking, adding a nice, distinct flavor to many dishes.
While Wild Chives are found wild in Indiana, they are just an escapee from your garden. They are native to more northern U.S; Washington, Idaho, Montana, Wyoming, Minnesota, Wisconsin, Michigan, New York and New England.
