Cold hardy Palm growth rate in hot summer, Zone 8b. 
W. Filifera and S. Mexicana averages about a foot per year. R. Hystrix much slower. In these observations.

@TonyDFW That is impressive for a Mexicana to be hanging in growth rate with Washingtonia. How bad did those 3 look after the 2018 freeze. My guess the Sabal had far less leaf burn ?
