These two, along a path, suggest spreading by walkers, original sighting and first 2 pics 1 Jan 2021. The top one is the southernmost, a bit further south along the path than the second, and doing well as of 5 Jan 2022. One in the second pic is also depicted in the 3rd pic, 5 Jan 2022, but has not managed to develop seed pods, perhaps due to competition with the grass, which is now very dense? One of the pods from last year's stem can be seen in the upper center, slightly to the left.
