Two views of an early spring non-native flower, one of the center, another an abstract of the petals:
I saw this buttercup relative today at Acton Arborteum, thanks to two volunteers doing a plant survey for a tagging project who told me where to look for it. There were only a couple small patches in bloom, some of them already gone by. It’s small and low to the ground. I hope it spreads, a group of them would make a great image. A much more interesting sight than the snowdrops that were also blooming.
