Smartweeds (Persicaria spp.) are ubiquitous in our summer landscapes, but individually they can be challenging to identify. Through this July 17 Native Plants Trust classroom presentation from 10:30 – 2 with Ted Elliman, a close look at herbarium specimens, and field observation at Garden in the Woods, you will learn the identification features that distinguish each of the 22 smartweed species in New England. $53 NPT members, $63 non-members.
