In an earlier post I came down pretty dogmatically against summering American frits in a plunge bed here on the east coast. While poking around in the garden yesterday, I realized that I have already done essentially that - and with good results. But the frit in question is Fritillaria camtschatcensis. I checked it yesterday and it's fine. It's not really in a plunge bed, but it is exposed to the rain and humidity. This plant is probably of Japanese provenance, not North American provenance, so technically I have not yet successfully summered a North American frit outside, exposed to summer rain.
