The Pacific Bulb Society is a world wide group interested in the cultivation of geophytes (plants with underground storage organs: bulbs, corms, tubers, rhizomes, tuberous roots, etc.) It sponsors the pbs list, an open forum for discussion of these plants and their companions. Pbs list members have created the PBS Wiki which can be accessed through the web page. The wiki is a growing resource of information and photographs of geophytes members are growing or have seen in the wild, in public gardens, or gardens of their friends.
