The only varieties I can find that say they have good cold tolerance

all Supersweets, and I had thought that Supersweets were more

in general than traditional varieties. Am I wrong about this? Would
I
be better off going for a quick-maturing Supersweet or one of the
older
varieties?

The "supersweet" varieties are all short and quick growing plants so
are the
ones to go for, heavy clay soil never caused us any problems on our
old
allotment with sweetcorn but we also start them off about the
beginning of
May in our heated greenhouse (min 55°F) in a multipurpose compost and
heated
propagator to start with.

Great, thanks for that. Have now ordered some Earlibird and looking
forward to growing it next year.
