The Dallas Chapter of NPSOT includes all of Dallas County and the twenty-two cities within its boundaries.
We are in the Blackland Prairie Ecoregion: Average rainfall 28-40 inches with peak rainfall usually in May, Hardiness Zone 8A, average annual minimum temps 15-10 degrees.
Wildflower Planting dates for our area are: Spring – January 15th thru March 1st Fall – October 1st thru December 1st
Our area is predominately an urban landscape, and the Dallas Chapter’s primary goal is to educate homeowners, businesses, and municipalities on the benefit of planting native landscapes. Each meeting, newsletter, field trip and activity will strive to achieve this goal.
Our meetings are the 3rd Monday of each month. If you cannot attend in person, the meetings will continue to be available on Zoom.
At the NPSOT Dallas meeting on May 15th, 2023, chapter members Nancy Wilson and Janet D Smith will present a program on the status of the monarch butterfly population and
