Members of the Four Rivers Garden Club will hold their 71st annual Flower Mart on Friday, April 29, at the Market House in downtown Annapolis. From 8 a.m. to 12:30 p.m. an assortment of native plants and perennials from members’ gardens as well as herbs and cut flowers will be offered for sale. May Day baskets will be available for pre-order or for sale the day of the event. A flower-arranging workshop at 9 a.m. will guide the novice in the creation of a May basket. Including supplies, the fee is $30 in advance, $35 for walk-ins. To register for the workshop or to order a May Day basket, please contact the FRGC at 443-995-2993 or firstname.lastname@example.org. Flower mart proceeds support grants to outreach and community garden projects.
