This crisply white plant grows in the Backyard Garden rockery bed. At one point it was classified as an aster and older field guides may still have it as Aster ptarmicoides. In more recent times it has been shifted over to the Solidago group. But whatever it is called, it is a lovely native plant that grows in the Ottawa region and deserves to have more of a place in gardens too. Bees and other insects are attracted to it as well.
