Re: sikki ''Daj giant'' ?
Some will be more resistant than others.
This winter, I test(ed) my Helens in my greenhouse. They all took a couple of freezes from -4 to -5*C. All my citrus can take those temps, so... no big deal.
My Helens are kept quite dry and the leaves (natural insulation once frozen) I did cut off. That way the stemhardiness can be measured.
My findings, so far, is that the black-stemmed ones are more tender (Chini-Champa genes). On the other side, one green one is unharmed by the frost.
It looks like they all going to pull trough, some more scarfaced than others. Nice hybrid!!
