This one has proven to be a real mystery, even when we asked a Master Gardener. Serrated edges, each cup 2-3 inches in width, about a foot in height.

Looks to me like a Sedum. The closest of the many varieties might be Sedum ellacombianum (also called Sedum kamtschaticum ssp ellacombianum)
Fresh green leaves and star-shaped yellow flowers in summer. 6” X 18”. Full sun, well drained soil. Very vigorous, almost weedy, drought and cold tolerant. A native of Asia and hardy to –30 degrees F or about (-30 deg C)
It is described in more detail here.
If I'm right it will have little yellow flowers.
