Along the quiet back stretch of the Beech Forest trail, a sea of serrated hearts has been patiently photosynthesizing since the spring, steadfastly preparing for its late summer show. The jagged cordiform foliage belongs to Eurybia divaricata, the white wood aster, a throng of which is now in dazzling riot along the Provincetown path. Whether viewed as an arresting protest to the summer’s end or as a heartbreaking acknowledgment thereof, this beautiful display can be enjoyed in every garden — white wood aster is a tough native that checks all the boxes and is available commercially.
