Make an autumn centerpiece that can be used for both Halloween and Thanksgiving, in this Tower Hill Botanic Garden class led by Betsy Williams on Saturday, October 24 from 10 – 12. Heirloom pumpkins are actually a hard-shelled squash. Flatter then Halloween pumpkins, they come in shades of celadon, forest green, cream and peach. An uncut heirloom pumpkin makes an elegant base for a striking harvest arrangement of richly colored dried flowers, herbs, grains, pods, nuts, mosses, berries and preserved leaves. The finished arrangement can be used as a harvest table accent for many weeks. All plant material, glues and Heirloom pumpkins are supplied by the instructor. Be sure to bring a pair of floral scissors and apron with you. Tower Hill members $75, nonmembers $90. Register online at www.towerhillbg.org.
