A joint initiative between Phipps Conservatory and the Orchid Society of Western Pennsylvania to create and cultivate an orchid collection of note for enjoyment, education and research.

September 2019

The Cypripedium Survey has been completed by eleven cyp experts. The data is being compiled to distribute so we know the most important Cyp hybrids and species for our Cypripedium Wish List for the Barbara Tisherman Slipper Orchid Collection, Phipps’ Living Museum of Slipper Orchids.


The P-OSI teams are studying the new Phipps orchid collection inventory to see how we can help Phipps update and grow their orchid collection in all ways, to continue to be one of special note.  Looking for a dendrobium leader.  Please let us know if you are willing to study the dendrobium inventory at Phipps and make your recommendations to improve the collection.

If you’d like to be a part of this phenomenal team effort, contact us!  We’d love to have you for Pfun and P-OSI!  It’s a wonderful learning experience for all of us, a great way to give back to the community and to help make Pittsburgh someplace even more special.


Our teams:

  • Phals/Vandas/Oncidiums

  • Epicatts/Catts

  • Dendrobiums/Cymbidiums
