I love Hot Cocoa but had to move it to another spot last year as the color clashed with other plants where I had it. It's a tall upright plant too so take that into consideration when placing it. I don't spray either and the foliage is nice, both the unique color and general good health convinced me to keep it rather than toss it when I dug it up.
My favorite in these colors is:
It looks so good with the Russian sage planted nearby as well as a couple of purple clematis
