Here is a plant I have growing in my garden. I forgot to label it and now am not sure what it is. I'm thinking it could be a Corydalis?? See photos; particularly the closeup of the unusual flower.
Could it be a Thalictrum species ? Maybe a male T. dioicum, early meadow rue ? I don't think it's Corydalis.
Oooh! I grow several Thalictrum but haven't see Thalictrum dioicum. Amazing stamens. Love it. NPSNJ Thalictrum dioicum Meadow rue - early Thalictrum dioicum page Thalictrum dioicum (Early Meadow Rue): Minnesota Wildflowers
