It means, that the corm of it is cold hardy, for the basjoo it is to HZ5, provided it is buried deep
enough. The top freezes off, where ever the frost penetrates into the cells. When the sap
freezes the water in it forms ice crystals, which destroy the cells from within. That explains,
why it has to be at at least -1^C (30^F) for a while before that happens. as I stated in one
of my posts, for which I gave you the URLs below, my basjoos have already suffered two
periods of frost this fall, one briefly at -1^C and one for a full 5 hours duration at -2^C
(28^F) and only the exposed tops of the leaves froze up.
