Some kind of fleabane maybe?
I have a dense patch of this in my yard, maybe 2-3 feet high. It's just starting to flower, will be covered with them later in the summer, then dies to the ground in winter. The flowers are aster-like to my eyes, but the foliage is almost more like an artemisia or something? The apps always latch onto one or the other and suggest something that doesn't match the other part.
