Full full west sun would be worse than south sun. but here's some stuff you can consider.
Zinnias, any variety of Celosia, Gomphrena, Amaranths, Tuberoses, Veronicas, Ornamental Grasses, Millets, Ageratum, Rudbeckia, Echinacea, Salvia, Tithonia.
Hope that helps MaryMargaret.

Zinnia, Sunflower, Rudbeckia, Aster, Scabiosa, Marigold, Celosia . . . almost any heat/sun-loving annual should do well in your area.

The most important part of gardening is the soil. With good soil you can compensate for other shortcomings, not enough water and/or sun in most cases.

I'm in Utah, zone 6-7. I've had great success growing the following on the west side of my yard which has no shade and gets beat upon by the sun most of the day:

daylilly, purple sage, thyme, honeysuckle, ice plant did surprisingly well last year, portulaca is very easy, geraniums love it.
