The Friends of the National Arboretum need help planting native shrubs and grasses along the newly restored Springhouse Run, a stream that runs through the Arboretum and into the Anacostia River. The stream has been beautifully restored with pools and riffles, rocks and waterfall and wide floodplain. Next up is planting thousands of native plants grown from seed gathered by the Arboretum staff and local garden clubs. Volunteer sessions are Nov. 8 and Nov. 18; 10 a.m. to 1 p.m. No experience necessary. Tools, guidance and some refreshments will be supplied. Register at fona.org/planting.
