Question
I believe this is a kind of Triadenum but I don't know which one of the two we have here in NH. I've posed the question on a Facebook Plant ID page and responses are mixed, with some thinking it may be a genetic mutant. It's along Butterfield Pond in Wilmot, NH, see on Thursday. There are quite a few plants that look like this, and also several that are what I normally think of as St. John's wort. Can you help? Thanks.
Answer
Dear mwms1916, your plant is Lysimachia terrestris (swamp yellow-loosestrife). The red-brown bulbils in the axils of the leaves is a good characteristic. While this species has minute dots on the leaves, they are dark (not translucent as in Hypericum). Best wishes.
