The fragrant Colonial Herb garden at the Wilton Historical Society will be the site of a gardening talk by herb expert Sal Gilbertie on Thursday, July 20, from 4 to 6. Gilbertie will speak on Microgreens and Super Greens, followed by a book signing, conversation, wine and cheese. All are welcome; there is a suggested donation of $10.

Microgreens, considered by some as a “super food,” are young plants harvested a few weeks after germination. They hold anywhere from four to 50 times the nutrients per volume as the same plants in mature form. Many can be easily grown in a kitchen, from radishes to corn.

Gilbertie, who lives in Easton, is a frequent lecturer on herb gardening and hosts year-round workshops at the Westport Gilbertie’s retail shop. He has appeared on numerous national radio and television programs, including Martha Stewart Living, Home Matters on the Discovery Channel, the Home Show on the Lifetime Channel and Sara’s Secrets on the Food Network. In 2011, he was named Connecticut Organic Farmer of the year by the Northeast Organic Farming Association.

He will bring three of his books to sell and sign:

Cooking with Microgreens: The Grow-Your-Own Superfood — provides step-by-step instructions for setting up a home microgreen garden, including an introduction to the major species and recipes in which they can be used.

Herb Gardening from the Ground Up: Everything You Need to Know About.

Small Plot, High Yield Gardening: Grow Like a Pro, Save Money, and Eat Well.

The Wilton Historical Society is at 224 Danbury Road.
