This March 25 Native Plants Trust program at Garden in the Woods in Framingham from 10:30 – 12:30 will discuss the sugar maple white ash forest communities that have such a remarkable diversity of native plants. The talk will cover the location of these communities in New England, their physical features, and, in detail, their flora. Threats to this community, such as invasive plans and the emerald ash borer will also be discussed. Ted Elliman leads the discussion. $30 for NPT members, $36 for nonmembers.
