It’s Valentine’s Day. What better way to celebrate than to admire the romance of plants. But plant sex? About as interesting as watching paint dry, right? Think again. The ways plants, algae, and fungi reproduce tell us a lot about how procreation has evolved over time. Join Elizabeth Farnsworth for this racy lunchtime lecture on the many interesting reproductive strategies these species pursue. Be prepared to blush. The New England Wild Flower Society class will be held at Garden in the Woods from 1 – 2:30, and is $14 for NEWFS and Mass Audubon members, $16 for nonmembers. Co-sponsored by that other edgy group, Mass Audubon. Register online at www.newfs.org.  Image from www.garden.org.
