Gardening is an institution here in Tulsa, Oklahoma, and today all gardeners worth their salt will 1) hit the opening of the Cherry Street Farmers Market (see above) and 2) mix and mingle at SpringFest. Look for a variety of plants available for sale, as well as garden art, crafts, food and fun for the entire family. Plus, Linnaeus Gardeners (basically, the warlocks of Tulsa gardening) will be available to answer any questions you might have about how to grow this or that. Through 4pm.
