Planting Wildflowers in the Big Country……

Q: When do I plant wildflower seeds in Texas?

 A: September through December are the months that are best for planting Texas native wildflower seeds, or wildflower seeds that are labelled for using in Texas.  Germination and growth will vary depending on species planted and environmental conditions.
