Arctic Frost and Orange Frost are the satsumas that were designated as Texas Superstars by A&M's horticulture gurus the last three or four years. First they are on their own root stock and second they have been tested to between 15-20 degrees. If they die back above ground and the roots are ok they will come back and still be good. Before moving from Huntsville I had both for two or three years but they were in the ground and didn't have any problems. I think they would be ok in CS in a pot depending on where it was located.
go to either the aggie-horticulture site or go to plantanswers.com and they should have good advice.
