In July, 2011, I gave my Sabal minor to another friend. It was store-bought the previous year and NOT "McCurtain County or anything special--all the nursery knew was it was from a wholesale nursery in Texas.
They planted it on a SE facing slope in East Central Oklahoma and have not watered or fertilized it, or protected it at all last winter, not even mulch.
Record heat. Record drought. (But: very mild winter.)
Results? Looks fine, growing. Here is a photo from Sunday.
Conclusion? Sabal minor are tough palms. No surprise.
