Norma has her lovely crocuses. I have these...
I have no clue what they are. They look a lot like dandelions, only a little smaller, and grow in wet marshy soil.
(ETA: We found an answer! It's coltsfoot - turns out to be a medicinal perennial, but it's also an invasive species. Just my luck that my first flower of spring is a noxious weed....)
