Interactive Last Frost Date Map for Texas
Using historical climate data from NOAA, Plantmaps has created a new interactive map displaying average annual last frost dates for Texas as well as major cities in Texas which will assist gardeners and growers with frost protection:
The interactive last frost date map can assist gardeners and growers trying to decide when to plant seeds, when to plant a garden and what type of plant frost protection to use.

I don’t know who runs this site, but it is very helpful and interesting. I love being able to look closely at the areas I focus on. Also the Texas frost map also has a native plant distribution mapping feature that is fascinating.
