Welcome to NPSOT-Williamson County

This site is under construction. Don’t rely on any content.

We are the Williamson County Chapter (NPSOT-Wilco) of the Native Plant Society of Texas, a 501(c)(3) organization. Our numerous activities provide nature education, outdoor recreation, and projects that help restore and beautify public and private landscapes in Williamson County, Texas. Our meetings and events are free and open to the public. We hope to see you there!

Monthly chapter meetings feature phenomenal guest speakers (the 2nd Thursday of each month — 7:00 to 8:30pm — Zoom & in-person). Our field trips, also monthly, might be local in Williamson County, elsewhere in Central Texas, or adventures farther afield. In the spring we hold native plant sales, working with local growers to ensure our inventory is suitable to the area. We post announcements in our Blog and on our Facebook
