I've grown this charming little anemone (like a pint-size version of A. blanda) for quite a long time, starting with bulbs from Czechoslovakia. Over the years I've put seedlings in various locations and this year I can see a huge difference in their performance in flower. The best are in a rich heavy soil under the eaves of a large witch hazel. Those under a deodar cedar, while they've lasted a long time, do not flower as well. Nor do those in a spot with brilliant summer sun. I believe the moral is obvious.
