Answer: Showy flowers can be coaxed into great displays when they are sheltered and/or supported against high winds, and protected from hungry groundsquirrels! Here are some suggestions I found in the latest issue of Rocky Mountain Gardener (http://www.rmlife.com/), sent in by a gardener who lives near Nederland, CO, at 8400': Annuals include cosmos, gaillardia, zinnia, nigella, phlox, salvia, nasturtiums, sunflowers, marguerite, cockscomb, sweet pea, calendula, California poppy. Perennials and biennials include tall daylilies, veronica, tall shasta daisy, sedum, johnny jump-up, bleeding heart, iris, tulip, daffodil, gloriosa daisy, geranium, penstemon. The list goes on. I suggest that you contact Rocky Mountain Gardener, and purchase one of their gardening guides, and perhaps hook up with other high-altitude gardeners for more first-hand advice. Best of luck!
