This plant has popped up in between the bricks in my walkway, and in the poor soil between the walkways. It gets partial shade and absolutely no attention. It's a pretty mound of green and yellow right now, and looks much better than anything I have tried planting in that spot (except for the Vinca major 'Variegata,' aka "scary vinca," that I have been regretting and pulling for two years now), so I'm going to pull it from between the bricks and try to encourage it in the soil.
