There are other names referred to in literature, but have no description I could locate. Those are not listed here. I would suspect that if one had a good colony established of all these selections, some would be the same plant traveling under different names, especially among the whites and blues. Yellow Wood Anemone Anemone ranunculoides is similar in all respects to nemorosa , including the root system. The flowers are slightly smaller in size, petals much heavier in appearance.
Color is a cheery yellow with a waxy sheen very much resembling a buttercup bloom.
This species is quite showy when an established colony is in bloom. It is early deciduous, going dormant around the last of June, along with nemorosa. There are a couple of selections to seek when collecting the yellow wood anemone. The one I received has blooms slightly smaller in size than the single. The tiny petals are so tightly crowded they remind me of yellow buttons.
