wood anemone 'Allenii'


The plant known as Allenii is a variety that belongs to the wood anemone family, which is a spring-flowering perennial known for its delicate and attractive flowers. This particular cultivar typically features blooms that are a striking shade of blue, rather than the white or pink commonly seen in other members of the wood anemone group. The flowers of Allenii are composed of petal-like sepals, usually numbering six to seven per flower, and they exhibit a slight nodding habit which gives them a demure and enchanting appearance. The center of each flower is adorned with a group of bright yellow stamens, which provide a lovely contrast to the blue sepals and attract pollinators. The leaves are deeply lobed, forming a kind of collar around the base of the flower stems, and have a lush, green appearance. These leaves are often divided into three sections, with further subdivisions that lend a fine-textured look to the foliage. Allenii spreads by underground rhizomes, forming carpets of foliage with the charming flowers rising above them in the springtime, creating a serene woodland aesthetic in gardens and natural settings. Overall, Allenii is celebrated for its beautiful spring display and its role in adding a splash of color to the shaded areas where it thrives.

  • water dropWater

    Wood anemones, including Anemone nemorosa 'Allenii', typically require moist, well-drained soil. Water these plants when the top inch of the soil feels dry to the touch. During the growing season, this may mean watering once every week, depending on the climate and weather conditions. It is important to avoid waterlogging, so provide about one gallon of water per square yard each time you water. During the dormant period, which is after the blooming in late spring to early summer, you can reduce watering as the plant requires less moisture.

  • sunLight

    Wood anemones like Anemone nemorosa 'Allenii' thrive in dappled shade, mimicking their natural woodland habitat. They can also tolerate full sun in cooler climates, but in areas with strong, hot sun, they should be placed in a location where they receive morning sunlight and afternoon shade to prevent scorching the foliage.

  • thermometerTemperature

    Wood anemones such as Anemone nemorosa 'Allenii' flourish in a temperate climate. They can survive a temperature range from about 20°F during winter dormancy to a maximum of 80°F in the active growing season. The ideal temperature for robust growth would be between 50°F and 70°F.

  • scissorsPruning

    Pruning is not typically required for Wood anemones like Anemone nemorosa 'Allenii', as they are low maintenance. However, removing spent flowers after blooming encourages more vigorous growth. It is best to tidy up the plant once the foliage has yellowed and died back, which is usually in late spring or early summer.

  • circleLife cycle

    Anemone nemorosa 'Allenii', commonly known as Wood Anemone, begins its life cycle as a rhizome underground, where it remains dormant during the winter months. In early spring, the rhizome sends up shoots which develop into distinctive trifoliate leaves and a single flower stalk bearing a blue-violet blossom. After pollination, which is primarily done by insects, the plant forms seed capsules that will typically ripen by late spring or early summer. Once ripened, the seeds are dispersed by wind or animals, which can lead to the growth of new plants in suitable conditions. Throughout the summer, the above-ground parts of the plant die back, and it enters a period of dormancy again, retreating to the underground rhizome until the next favorable spring season arrives. Each year, the cycle repeats with the rhizome growing larger and potentially producing more flowering stems.

    • Propogation time

      Spring to early summer

    • Propogation: The Anemone nemorosa 'Allenii', commonly known as the Allenii wood anemone, is best propagated by division, a process most effectively carried out in the fall after the plant has finished flowering and when the plant is dormant. To propagate by division, carefully lift the clump of rhizomes from the ground and gently separate them, ensuring that each division has at least one growth point or bud. These divisions should then be replanted immediately at the same depth they were previously growing, spacing them about 4 to 6 inches (approximately 10 to 15 cm) apart to allow for adequate growth room. The soil should be kept moist but not waterlogged to encourage the rhizomes to establish and grow. The process is relatively straightforward and allows gardeners to quickly increase their stock of the beautiful Allenii wood anemone.
