Early Frost
I have my wireless weather station right next to the dahlia bed. A few nights ago, the neighbor's roof had a little frost on it in the morning, but the dahlias survived. I measured a low temperature of 33 F. Last night's low temperature was 30 F, and it turned the dahlia patch black. Guess they are not frost-hardy, not one bit.
In 2006, the dahlias lasted over three weeks later (November 5) (http://pedicularis.blogspot.com/2006/11/frost-damage.html).

can you send some frost down here please?
;-)
The dahlias you gave us are blooming quite nicely now. I guess it helps to be within 400' of sea level (and within three miles of the sea). No frost here.
Lots of white, but also yellow, orange, and a couple purples -- including one bloom that's 8" across! I should take some photos.
