While the common name for this plant is 'Japanese Anemone', this plant came from China. Go figure...
A tough herbaceous perennial, we sparingly plant Japanese anemones. The reason for this is, with our benign PNW climate, these plants can become aggressive over time. Do not site this plant near more delicate 'brethren'! It will eat them for dinner.
That said, the various autumn flowering selections require very little maintenance and flower for an extended period of time (and at a time of the year when many plants are looking a bit dingy). Do not plant in too deep of shade, as this plant will not flower, but will continue to grow (miserably, but persistently).
