Rock Garden plants

This is a collection of plants that I find very hardy and easy to work with. They are all suited for trough gardening or rock gardens. Most need full sun with excellent drainage. I have made notations on the individual plant description of those plants that vary in their cultural needs. All photographs are from Sunny border and Walters Garden. We will add the pictures we are missing when the weather warms up enough to take pictures. Updated for 2010
