Native to China, Anemones have been cultivated in Japan for hundreds of years. They consist of the species Anemone hupehensis, Anemone hybrida, Anemone tomentosa and Anemone vitifolia, as well as their subspecies and cultivars. Most of current cultivars are attributed to Anemone hupehensis and Anemone hybrida.
Well suited for borders, cottage gardens, coastal gardens or naturalized areas such as prairies or meadows, Japanese Anemones bring life in the late summer garden and persist to contribute to the crescendo of fall.
- Japanese Anemones thrive in partial shade. However, please note that too much shade can result in leggy plants that flop over more readily. Full sun is tolerated as long as the soil is kept moist.
- Japanese Anemones perform best in rich, humusy, evenly moist, well-drained soils. When planting them, add garden compost or aged manure to the soil and do not let it dry out. Avoid excessive winter wet. Add mulch each season to maintain soil moisture, keep weeds away and ensure winter survival in cold winter areas.
- Japanese Anemones can take 1 to 2 years to establish, but once they do, they can spread rapidly by rhizomes and happily naturalize to form colonies. The more sun they get, the faster they spread. While their rhizomatous habit may be desirable in larger landscapes, they may out-compete other surrounding herbaceous plants. Fortunately, removing any unwanted sprouts is easy.
- Though they may appear delicate, these long-lived perennials can survive with minimal maintenance once they are established. Very attractive as cut flowers, Japanese Anemones enjoy a good resistance to most insects and diseases and are salt tolerant. They attract butterflies, but are deer and rabbit resistant.
- Plant them in spring after all danger of frost has passed, until early fall.
- Japanese Anemones may require division every 3 years if grown in sun but as seldom as once a decade if grown in shade.
- Propagate by division in early spring or fall, or propagate by root cuttings.
- Cut back in late fall
- Eating may cause stomach upset and skin contact may cause mild irritation.
