Welcome to the Wyoming Native Plant Society (WYNPS). Our goals are to encourage the appreciation and conservation of the native flora and plant communities of Wyoming through education, research, communication, and field trips.

Activities include the annual
summer field trip, other native
plant walks around the state,
and the occasional virtual
events. MORE »

Membership is open to
individuals, families, and
organizations, including libraries,
with an interest in Wyoming’s
plant life. MORE »


April is Native Plant Month in Wyoming! Governor Gordon has once again officially proclaimed April as Wyoming Native Month. Let’s all get out the word about the value of our indigenous flora. Poster winners have been chosen! This was a tough contest, with many beautiful entries.

We look forward to seeing you at the 2024 annual meeting, June 13-15, in Morton, WY. Watch for information on our Events page and in the next issue of Castilleja.

The May issue of Castilleja is now posted.
