You might decide to plant anemones in your garden if you want a colorful, summer-blooming plant. Another kind of anemone is a "sea anemone," which is not a plant at all, but a flower-like sea creature that attaches itself to a surface and feeds on fish and crustaceans. Anemone is a Greek word that means "windflower" or literally "daughter of the wind," from anemos, "wind," and the feminine suffix -one.
