  • Question

    I came across this plant along the shore of the Charles River in Dedham. There is an abundant population, so I first assumed it was one of the more common Cardamine species, but none of the basal leaves are deeply lobed. Some of the larger leaves have me confused about how to key this one - are those teeth or lobes? If I call them teeth, my tentative ID is Cardamine bulbosa. Am I close?

    Answer

    Dear stephradner, your plant looks like Cardamine bulbosa. In this species, the basal leaves are without lobes (so your observation is in line with this species). So, you are very close with your initial hypothesis. Best wishes.
