Wow! Double-bind!
I envy you guys for being able to grow cyps in your yard

BUT I sure do not envy the weather that you have to live with!

But I have grown both
C. reginae and C. calceolus parviflorum in pots here in sunny

central coastal California!
Here is a link to a page of those that
I grew many years ago.

Cypripediums
I have only recently (2005) gotten back into trying and have a C. reginae and a C. kentuckiense in my frig for the winter rest.
They are only 2 years old.
