Andrew Keys, author of Growing the Northeast Garden, discusses underused and overlooked plants for gardens specifically for our region. The event will take place Sunday, May 17 from 1 – 3 at Tower Hill Botanic Garden. He’ll include plants from his book that are widely available but tend to be overlooked by gardeners, as well as “b-sides”–botanical outtakes from the book, rarer in nurseries, but sure to interest the horticulturally curious. An illustrated lecture will be followed by a walk to view many of these plants in Tower Hill’s gardens. $20 for THBG members, $30 for non-members.
