Growing thickly under a stand of staghorn sumacs. At one time, this plant was in the open, but the sumacs have spread and the lamium too. About a decade ago, Claudia and I dug out every lamium plant we could find, and then did it again the following year. The year after that, I dug out some but it was clear it was a losing battle. This is a resilient, non-native species which I think, came in with leaves which were put here at this spot about 20+ years ago. People donated the leaves from their gardens for us to use as mulch and inevitably, some other plants such as this, came in with the mix.
