Thanks for the tips. Of course I would be thrilled if any cycad would stay evergreen at my single digit minima. This winter despite one morning at +9 deg F and another at +11 deg F only about 10% of my Panzi's leaflets burned-only the 2nd winter out of 6 it has stayed evergreen. So where to I get the appropriate ecotypes to test? From you?
