  • water dropWater

    Japanese anemone, specifically 'Splendens', requires moist, well-drained soil, so regular watering to keep the soil consistently damp is important, especially during dry spells in the growing season. They should be watered deeply about once a week, applying roughly 1 gallon of water per plant each time. This frequency may increase to twice a week during periods of drought or particularly hot weather, ensuring the top inch of soil doesn't dry out between watering sessions. Avoid overhead watering to reduce the risk of leaf diseases and apply water directly to the base of the plant.

  • sunLight

    For the Japanese anemone 'Splendens', light conditions that promote the best growth are part to full sun in cooler climates and part shade in hotter areas. They thrive in a location that receives morning sunlight and is shaded from the intense heat of the afternoon sun, which can be especially beneficial to prevent wilting during the hottest part of the day.

  • thermometerTemperature

    Japanese anemone 'Splendens' prefers temperate climates and typically fares well in temperatures ranging from 50°F to 75°F. They are hardy and can survive temperatures as low as 20°F and as high as 80°F, although extremes outside this range can stress the plant.

  • scissorsPruning

    Pruning of Japanese anemone 'Splendens' is primarily done to remove spent flowers and encourage additional blooming or to maintain its shape. Deadheading, or the removal of old flowers, should be done regularly throughout the flowering season. In late fall or early spring, cut back the stems to ground level to clean up dead foliage and make way for new growth.

  • circleLife cycle

    Anemone hupehensis var. japonica 'Splendens', commonly known as Japanese anemone, begins its life cycle when seeds are dispersed and germinate in spring, developing into small seedlings with rudimentary leaves. The seedlings grow into clumps of foliage, forming a basal rosette of leaves at the soil level and expanding through underground rhizomes. During late summer to fall, the plant sends up stalks that bear the distinct pink to purple flowers, which are pollinated by insects. After flowering, seeds are produced and distributed by wind or animals, allowing for new plants to grow the following season. In winter, the aerial parts of the Japanese anemone die back to the ground, while the root system remains dormant underground, storing energy for the next growth cycle. With the onset of spring, the plant emerges again from its rootstock, renewing its life cycle with fresh foliage and preparing for another season of flowering.

      Late summer to early fall

    • The Japanese anemone 'Splendens', a beautiful fall-blooming perennial, is often propagated through division in spring. This popular method involves carefully digging up the parent plant as it comes out of dormancy and the ground has thawed, then gently separating the clump into smaller sections, each with several shoots and a portion of the root system. It's important to replant these divisions quickly to prevent the roots from drying out. Position them at the same depth they were originally growing, space them about 18 inches apart (approximately 45 centimeters), and water them well to establish. Division helps to rejuvenate older clumps that have become less vigorous and is a reliable way to produce new plants that are true to the parent in form and bloom.
