Moisture tolerance of aril irises

The aril hybrid irises that I've been growing under cover for a 
number of years have taken so well to the freedom of the raised beds 
in my bulb house that they are crowding out other plants. Most of 
them are hybrids between the Oncocyclus and Regelia sections. I'd 
like to move them into the open garden but I don't want to doom them 
to death in the wet winters of the Pacific Northwest. They would be 
dry from about mid-June to late September in a typical year.

Does anyone have experience growing these plants in a winter-wet 
climate without overhead cover? How well have various cultivars done? 
Some of my favorites are
''Thor', 'Cythe', and 'Peresh'.
