RGC Membership Merchandise Riverside Garden Club members now have access to purchase garden club themed merchandise. Check out the various selections of pullovers, shirts, jackets, bags and hat all with our lovely logo. Some items are available in multiple colors. Next to each item you will see a product number. If the number begins with “LST”, it means it’s a ladies cut. If it starts with an “ST”, that means it’s a unisex cut.
