I think you're going to have to be a little more specific. What kinds of plants? Vegetables? Flowers? What kind of flowers? Annuals? Perennials? Be more specific and you'll get all kinds of answers :bouquet
Cherndon (is that Cher 'n' Don?), the University of Wyoming has a 25 page pdf file on "Gardening: Vegetables in Wyoming." They've really emphasized short-season varieties and I thought the idea of using windbreaks and fences is a good one !
Food storage info may also come in handy.
Hope it helps a little. I'm in a not-such-different area but not-quite-the-same.
Many seed and plant catalogs will give you a hardiness zone for their products. I once saw a Victory Garden episode where they showed a man in ALASKA that grows giant vegetables. He had an amazing system. Can you believe it would be worth gardening there?
A friend of mine has a relative who lives near anchorage, and yes, they grow huge things. Not far from the coast, protected spot, and mosdst of all, really long days in summer, plus large gradient in day length.
