There are about 25 species of Desmodium, Hylodesmum, and Lespedeza in New England. These summer-blooming members of the legume family often look alike, presenting challenges to identification. This Native Plant Trust class on July 28 at 1:30 pm at Garden in the Woods will focus on the features that distinguish each species and discuss their ranges and habitat preferences. $38 for NPT members, $45 for nonmembers.
