One late summer stunner is the hardy Fuchsia. For those with mixed garden conditions - some sun, some shade, some of everything in between - hardy Fuchsias are excellent for providing a continual source of color from late June until the first frosts of late October and November.
Way up here in the land of tall conifers, dry shade is a common gardening challenge. I’ve had success with the following plants in the shade of conifers, and they also work well in deciduous woodlands or in the dry rain shadow of north-facing buildings and garden walls. As with any new plantings, they will require summer water for several dry seasons until they have established a root system capable of competing with existing tree roots.
