But I've had good success with Stupice up here in Canada.
About as good are Kootenai, Siletz, Big Beef, and Fantastic,
all available from West Coast Seeds (wwwwestcoastseeds.com).

I grow mine under the eaves on the south side of a white
stucco house in a raised composted bed. Here, in Vancouver,
our big problems are rain (which is why they're under the
eaves), and slugs (which the raised bed framed by 4X4s
discourages).

My reading says that one of the blights is caused by wet
leaves. So I don't let them stay wet overnight. Which is
why I shelter them under the eaves, but in direct sun,
enhanced by the reflectiveness of the white stucco.

This year, I didn't do my usual seed starting, and bought 3
varieties from the local Safeway which didn't get planted
until June 5th! Didn't expect much as they looked so feeble
compared to my home-growns, but at this point they look great.

Best is Ball Extra Early (which I can't find in my seed
catalogues). It's now quite large with lots of fruit. Next
is Super Fantastic. Worst is Oregon Spring.
