This is a volunteer-written encyclopedia about flower bulbs. You'll find information on thousands of bulb species (with photos in most cases), plus selected hybrids. We also cover related topics like how to grow them, how to obtain them, our personal favorite bulbs, and where to see them in the wild and in gardens. We include all "geophytes:" plants with an underground storage organ such as bulbs, corms, rhizomes, and tubers.
The common bulbs you can find in a garden center are nice, but pale in comparison to the beauty and uniqueness of many species bulbs and their lesser-known hybrids. The photos you see here are just a sampling of the incredible diversity that's out there waiting for you to discover it. Many of these gorgeous plants are easy to grow, but almost unknown in cultivation. What’s worse, many of the species are also threatened with possible extinction as their native lands are developed into buildings and farms. We’re devoted to spreading information about these plants, and teaching people how to grow them and keep them alive.
This guide was created by the members of the Pacific Bulb Society e-mail discussion list, a group of people from around the world who are interested in growing and gardening with bulbs. Our members range from experts to beginners. Membership in the e-mail forum is free, and open to anyone. Click on the link for more information on the forum, and also to search the archives of our online discussions.
You're also invited to join the nonprofit Pacific Bulb Society, which conducts seed and bulb exchanges, and publishes a quarterly newsletter on bulbs. Your membership fee helps support the society’s activities, including this wiki.
The centerpiece of our wiki is the index of all the photographs and information we’ve posted about bulbs. This is the place to go if you’re looking for information on a particular bulb species or genus. (Please note that the photographs in this wiki belong to the people credited on the wiki pages, and may not be reused or reproduced without their permission.)
