Specialized plant groups can be valuable resources to gardeners who want to explore subdivisions of the gardening world. Here in Colorado there are a host of organizations with special focus, from African violets and orchids to daylilies and dahlias, from water gardening to carnivorous plants. In these groups one can tap into a wealth of information, practical experience, and passion for particular plants and styles of gardening. Most of them are also a source of plants.
This weekend took me to the Colorado Cactus and Succulent Society's show and plant sale at the Denver Botanic Gardens. I'm planning a non-irrigated ornamental plot in my backyard and expect cacti and succulents to play a prominent role. So this seemed a good chance to get started.
