Cold tolerant lime

[Mark in Texas]

Texas citriculture:

"True lemons and limes are too cold sensitive for commercial plantings in the Valley, but a few acres of Meyer lemon are grown for local use."

Why in this case limes are practically absent in commercial planting in Florida?

I suspect it is the same reason we have a lot of backyard citrus (mostly Satsuma) , but little to no commercial citrus here where I live in SW Louisiana along the 8b/9a line.  Risk aversion, you never know when that 50 year freeze will come along and wipe out 100% of your trees.  Also with backyard citrus there is a better chance of surviving that 30-50 year freeze through covering, christmas lights, etc.
