Current issue of The Dodecatheon

July-August 2024


We are a group of gardeners immersed in the world of rock gardening. We are eager to share our interests, knowledge, and plants with others.

Through meetings, garden tours, plant sales, and workshops, our group provides members with the opportunity to dig deeper into gardening. We are interested in plant cultivation and propagation. Our members enjoy rock gardens, alpine gardens, troughs and other containers, raised beds, bog gardens, gravel gardens, woodland gardens, native plant gardens, and more.

Our location is the greater Philadelphia area. Membership is open to all, and the first year of membership is free. Download a membership form.


We meet monthly from October through April, generally on the second Saturday of the month at 10 AM. Each meeting features a well-informed speaker on plants or gardening. Speakers are sometimes internationally recognized experts and sometimes local experts knowledgeable about gardening in our region. This year's meetings.
