I'm looking for suggestions for low-growing, sweet-smelling, hopefully colorful foundation shrubs. My white, 1925 home faces the west. It gets lots of sun, but it's shaded by about 4 pm. The porch is about 2 ft off the ground. I'd really like a fragrant shrub, but lower maintenance and maybe more color than gardenias. (I can't keep gardenias alive -- too much black sooty stuff from aphids, I guess.)
