Learn to create delightful winter pleasures from summer’s abundant gardens: how to air dry, silica dry and dehydrate flowers for fall and winter decorating; the step-by-step tricks of preserving the green leaves of summer with glycerin; and the many ways to keep and package herbs for the winter kitchen and gift-giving season. It’s fun, easy and satisfying to capture the beauty, flavors and fragrance of summer for winter use! For our Garden Club of the Back Bay wreath project, these blossoms will be invaluable.  The class will be held at Tower Hill Botanic Garden on Saturday, August 9, from 9:30 – 12:30, and will be taught by Betsy Williams.  THBG members $60, nonmembers $75.  Register at www.towerhillbg.org.
