About Us

Since 1959, the Great Lakes Chapter of the ARS has served its members by promoting education and research on rhododendrons and azaleas while fostering friendships and collegial exchange of information throughout the year. We host formal meetings in the Spring and Fall at members’ private gardens as well as at nationally recognized botanical gardens around the Great Lakes Region.

From pure whites to pretty pinks, bold reds, fiery oranges and soft purples, rhododendrons and azaleas put on a spring show in color and shapes unrivaled by none. And, in the darkest days of winter, their lovely green leaves peek out from under the snow, giving us hope of what’s to come. if you are a beginner just learning that ‘“rhodies” love acid soil and hate wet feet, or an accomplished gardener looking to create your own hybrids, our chapter can provide you with the guidance and tools you need to pursue your goals.

“The Great Lakes Chapter of the ARS has something for everyone. Whether you’re into rhododendron for the flowers, conservation, conversation, preservation, plant physiology, hybridizing, research, art, or the medicinal properties of the shrub, there’s a place for you in the group.”

— Ellen Dailey, GLC Member
