TexasColdHardyPalms Posted February 14, 2017 Report Share Posted February 14, 2017 During this winter I have noticed a big difference between seed stock of Sabal Uresana and upon further investigation it appears that there are two distinct populations of this species. The costal form is more blue/green in color and from what I can tell is more of a zone 8 palm. I have had various damage on this species from 100% defoliation on smaller 5G plants in the ground to 75% defoliation on larger 5-6' tall (overall) plants in the ground. There is also a reported Mountain form that is silver/white even from the first leaf (same color as a B. Armata) and this palm appears to be zone 7 hardy. I had zero damage on three leaf plants in 1G pots (100% frozen) at 16F and 30+ hours below freezing. This form is much hardier than the Rosei or Riverside (both 100% burned at this temperature. 6 Link to comment Share on other sites More sharing options...
