Small shrub for afternoon sun, western exposure?
I am looking for shrub suggestions for a small bed that is next to the sidewalk in the front of my house. I currently have some Irises, ornamental grass, peonies and artemesia planted in the bed, along with some ground covers and a shrub rose. I would like to find a small shrub for the center of it.
There is a large white poplar behind the bed (NOT something I planted but it's way too big for me to have it removed - can't afford it.... :-o ) so it gets shade to dappled shade in the morning but in the afternoon it gets the full blast of the sun with western exposure. The soil is alkaline clay.
By "small shrub" I mean that I want one that will only get about 4' tall by 3' wide and, of course, I want it to have four season interest, but that is in a perfect world so I don't know that such a thing exists.
Any suggestions, or should I just fill it up with perennials?
