Botanical Society of Western Pennsylvania


The Botanical Society of Western Pennsylvania (BSWP) is one of the oldest botanical organizations in the country. Since 1886, our members have met, botanized, and served as a resource of knowledge on the plants of Pennsylvania.

Membership in BSWP is open to those who are interested in botany and who wish to encourage the study of this science and a knowledge of plants. Our membership comprise a diverse group, including botanists, teachers, naturalists, photographers, artists, and gardeners.

General memberships are available on a yearly basis, renewing in January, and include:

  • a subscription to BSWP's quality newsletter, Wildflowers
  • notice of our monthly meetings, held September through June at the Carnegie Museum of Natural History in Pittsburgh, featuring topics of botanical interest.
  • notice of our excellent field trips held throughout western Pennsylvania.
  • support of botanical programs such as the Pennsylvania Botany Symposium, Celebrate the Bloom! at Jennings, Enlow Fork Extravaganza and the Education Scholarship Fund for the Carnegie Museum of Natural History.

Annual dues are $16 for individual, $21 for a family, $35 for a sustaining membership. All school, college and postgraduate students can join for $8. We now have a lifetime membership for $150.00.
