A wonderful long-blooming aster that is probably the most common plant in the drier areas of Dimple Dell Park.
To me, it seems closer to H. utahensis, but could possibly be H. zionensis. However, I tentatively agree with the discussion on this observation that the distinction between the two seems arbitrary.

Pretty rare in the county I think.
