About the Connecticut Botanical Society

We are a group of amateur and professional botanists who share an interest in the plants and habitats of Connecticut and the surrounding region. The society was founded in 1903. Our goals are to increase knowledge of the state's flora, to accumulate a permanent botanical record, and to promote conservation and public awareness of the state's rich natural heritage.

Botanical Society Activities

  • We run field trips, led by knowledgeable botanists, on weekends from spring to fall. The trips provide a great opportunity to learn about wild plants and about the state's diverse ecosystems. Field Trip Schedule.
  • We hold meetings in spring and autumn, each with an illustrated lecture by a naturalist or other scientist. Next meeting.
  • We publish a quarterly Newsletter with botanical articles and news.
  • We created the Connecticut Botanical Society Herbarium, a "dried plant library" with over 36,000 sheets of plants. This collection records the changing distribution of Connecticut flora.
  • We created and maintain the Vascular Plants of Connecticut Checklist, a comprehensive list of plants that grow wild in the state. The list is available free for download at Vascular Plants of Connecticut.
  • Along with the Connecticut College Arboretum and the Connecticut Urban Forest Council, we collect and distribute information on Notable Trees: the state's historic trees and its largest trees.


Connecticut Botanical Society is open to anyone interested in plants, conservation, and natural history. Non-members are welcome to attend our field trips and meetings before joining. Membership information. white oak leaf
