New USDA Plant Hardiness Zones

Bedford (and most of north Texas) is now in Zone 8a of the USDA plant hardiness zone map. It was recently revised based on data for the "average annual extreme minimum temperature 1976-2005."

The map covers the country. It is a fine tuning of previous maps based on increased data.
