Don't worry - I didn't turn into a brilliant botanist overnight, so if you didn't recognize the name, I didn't 10 minutes ago either. This happens to be the Latin name for the marsh marigold (which I googled). Two days ago, my marsh marigolds were being blown around and covered with snow by the blizzard. You can see from these photos that they suffered no ill effects.
I dug these up from a swamp, er, wetlands, near our house a few years ago and relocated them to the edge of the pond. All 5 plants are doing well . By the time they're finished blooming I hope my pond irises will be ready for their show.
