Dicentra cucullaria, although I prefer the common name, “Dutchman’s breeches.” Visually, it reminds me of the “bleeding heart” in my backyard garden, although there is no direct relation; my “bleeding heart” is the Asian variety, not native to North America.
I found this Dicenta last spring, growing along the trail at the Rowlands Preserve. I’m eager to see if it has returned! It was an unexpected find and helped kick off my interest in spring wildflowers.
