Monty says, before you plant out a new anemone plant, take some root cuttings before you plant the main plant out. Set the root cuttings out vertically onto the surface of soil, and then like all cuttings, cover in grit. Water, and put into a cold frame. This way your new plant is true to the original parent plant.
Japanese anemone are brilliant plants for dry shade, with good drainage. We may have to plant some into the new beds in the woods which nominally are planted in memory of Ayla Larke and Mary Barnes, who died within a year of one another. Mary was in her 90s and Ayla only in her 60s, but were both founding members of the Lismore Circus Community Woods.
Monty also warns that sometimes anemone don’t do so well in their second year, and often take time to settle in. But they are long-lived plants with a long flowering period, so well worth the patience.
