Thanks Donald! Apparently
Pindo Palm (Butia capitata) is pretty hardy and can survive temp's to as low as @ 15ºF! Wikipedia says it grows as far north as N.Y. on the east coast and as far north as Washington on the west coast ... I'd say that's one very hardy palm!
I've never tasted the fruit but my dog tries to eat it when it's all over the ground beneath the trees!
