About plant names...

The toothed white-topped aster is a North American native.

Identification: As asters go (there are zillions of different kinds), these are sort of disheveled-looking, at least the ones I’ve seen. I don’t mean to pick on them, but they are easy to overlook at first. Toothed white-topped asters are 6-26" (14-65 cm) tall, with stems covered with soft, downy hairs. Leaves are roughly oval-shaped, smooth-edged toward the bottom, rounded toward the tip of each leaf. Each flower consists of a central disk flower that is off-white, and four to eight white petals that form the ray flower. Flowerheads are ½" (1.3 cm) across, occurring in small clusters. They flower between June and October.
