We are a group of Rock Garden enthusiasts with nearly 200 members, mostly in Michigan. We focus on plants of the Alpine regions of the world but never turn down a chance to grow any unique or interesting plant. Why not join us?

From garden tours to plant sales, our members enjoy sharing their knowledge and passion in this type of horticulture. We have speakers and programs that span the globe, with experts from as far as Europe, South Africa and New Zealand to our very own members, all united in the pursuit of rock gardening.

Fall Plant Sale and Garden visit
at the garden of Ed and Colleen Weiss in Ann Arbor, 1005 Fairmount, Ann Arbor, MI 48105 — see [Newsletter]:
11:00–ca. 1:00 tour the garden; BAG LUNCH: While touring the garden; PLANT SALE: 1:30 PM — See the Plant Sale insert for details.

(Note this meeting is the 23rd not our usual date of the third Saturday in September.)

Ed and Colleen Weiss are pleased to host. Relatively new to the world of Alpines, they have been planting these fascinating plants over the past five to six years. Their introduction to the plant world began with their collecting unique and diverse conifers. All this planting activity takes place in and around large boulder walls creating a unique back-yard environment. The Alpine garden is a work-in-progress that begs complementing the conifer slogan “I haven't met a Chamaecyparis I didn't like” with “There isn't a Saxifraga we wouldn't plant”.

Business Meeting, Talks 12:00-12:45 pm and 2:30-3:30 pm, and Membership pot-luck
at Matthaei Botanical Gardens auditorium in Ann Arbor, MI

Kenton J. Seth gave two fascinating (45-minute -- the first went rather longer to the audience's pleasure) talks. One on “Crevice Garden Construction” beginning followed by our membership’s pot-luck lunch, and the second presentation “Wildflowers of the Caucasuses”. Both lectures were well attended. In addition there was a demonstration of grafting (a peach on a cherry) by Andy Duval and an auction of some donated books and choice plants (particularly 2 Hamamelis in bloom from Duval).

Kenton Seth is a young native of Colorado. He is a plant nut and native plant hunter who has worked in public horticulture and nurseries. Kenton currently owns Paintbrush Gardens, a dual specialty landscape company which builds un-irrigated native landscapes and crevice gardens for public spaces. Kenton also documents his adventures on his blog “I Need A Cup of Tea”. In addition, you can look at a YouTube video from a crevice gardening workshop by Kenton at the J. C. Raulston Gardens in Raleigh NC
