Answer: It is a bit late to be planting things in your garden. You should be able to find some colorful annuals in local garden centers for some instant splashes of color. There are a number of plants you can include in your garden at 9300 feet. In fact, Colorado State University has put together an informational website that I think will be helpful to you. It has lots of lists of plants, plus some ideas for extending your gardening season. Here's the web address: http://www.ext.colostate.edu/pubs/garden/07406.html
