The term Aster Seeds is a little misleading since the North American wildflowers that we list are now categorized in the genus Symphyotrichum. This genus name is a bit of a mouthful, and the flowers still have to be compared to Asters, so we've chosen to cut this botanical corner. Either way, this group of plants is found across Canada and the United States and blooms later in the season, supporting pollinators in late summer and early autumn.
