My experience with the one I got from Sacha and Ray was that it went black
at the mention of frost, most annoying when it was up to the bedroom windows
and just about to open it's buds.

That's the D. imperialis. It's just not as good a plant from that pov as
the D.excelsa. It's a true tree Dahlia, granted but it's not a patch on D.
excelsa for flowering and toughness. In poor weather i.e. wet summers with
little sun, it might grow like a weed but try to get it to flower.......
