Japanese Anemone
Anemone x hybrida
An elegant, clump-forming perennial producing saucer-shaped flowers in shades of white and pink on tall, wiry stems from August to October. Japanese anemones are invaluable for late-season colour in partially shaded UK borders. Once established, they spread steadily via underground runners to form impressive colonies, thriving in conditions that defeat many other flowering perennials.
How to grow japanese anemone
Plant in spring in moisture-retentive soil in partial shade, though they also perform well in full sun if the soil stays moist. Space plants 60 cm apart and water regularly during the first two seasons whilst the root system establishes — they can be slow to settle in. Once established, Japanese anemones are tough and self-sufficient, spreading steadily to fill gaps. Mulch annually with garden compost in spring. Avoid planting near delicate neighbours, as the underground runners can be vigorous and difficult to remove once entrenched. They tolerate clay soil better than most perennials, making them ideal for heavy UK soils.
Pruning
Leave the fluffy seed heads standing through early winter for interest. Cut all stems back to ground level in late November or December once the foliage has died down completely. No other pruning is required. Control spread by digging out unwanted runners in spring.
