If I can be of more help or answer more questions about Murphy, NC just let me know!
As for our home which is 23 miles south west of Murphy, we do not have to take any of our bulbs out of the ground for the winter. We have been told that our home is on/in a "thermal zone" and that there are many in NC. Amazing what grows here. And in the 6 years we have lived here we have had very little snow.
