Tabby,
You might test some of the spathufloiums out as some are from rather cold areas of OR, like the Siskiyous. Clausen lost them in Ithaca NY to, but that is VERY cold there, probably Zone 4. I think they are the most beautiful of all the sedums and a treasure of our American wildflowers too.
When it stops raining I'll get photos of the other pinkish ones. I will probably put at least a couple of these on the market. Everyone that has come to the yard has enjoyed them. I am growing Helen's 'Harvest Moon' as a comparison as she thought it was the best of these.
Cool here today. Am going to make a pot of soup!
