Jim SHields asked, >How hardy is Iris wattii? I have not been able to keep it through the winter here in the Cascade foothills east of Portland, Oregon, despite putting it in the warmest place in the garden, so I think it may not survive temperatures below 20 F/minus 7 C, at least when wet. (And it is VERY WET here right now, has been pouring for 3 days with more to come.) Jane McGary NW Oregon
