Japanese Anemone Anemone × hybrida 'Whirlwind'
ABOUT
The Anemone × hybrida 'Whirlwind' is a perennial plant known for its appealing late summer to fall blooms. It features semi-double flowers, which mean that they have more petals than single flower varieties but not as many as fully double ones. These flowers are white and tend to have a somewhat ruffled look that gives the plant a sense of movement and delicacy. The center of the flower is yellow, with numerous stamens that attract pollinators. The foliage of 'Whirlwind' is deeply cut and dark green, providing a beautiful backdrop for the flowers. The leaves are divided into three lobed leaflets, giving them an attractive, fern-like appearance. This foliage contrasts nicely with the bright blooms and adds texture to garden settings. The Anemone × hybrida 'Whirlwind' blooms on upright stems that sway gracefully in the breeze, contributing to its common name of windflower. The stems are sturdy and hold the flowers well above the foliage, creating a layered effect in the landscape. The flowers are often used in cut flower arrangements due to their beauty and long vase life. This plant brings a light and airy quality to garden beds and borders, and its blooming period helps to extend the garden's interest into the cooler months of the year.

Life cycleAnemone × hybrida 'Whirlwind', commonly known as Whirlwind Japanese anemone, begins its life cycle as a seed, which upon germination, develops into a small sprout with characteristic foliage. The plant establishes a clump-forming perennial root system, allowing it to overwinter and emerge each spring with renewed growth. As it matures, Whirlwind Japanese anemone forms tall, branching stems topped with large white, semi-double flowers from late summer into fall. After blooming, the flowers produce dry, achene-like fruits that disseminate seeds for propagation. In winter, the above-ground parts die back with the onset of cold weather, though the plant survives underground through its hardy rhizomes. The cycle repeats as temperatures warm in spring, prompting new shoots to rise from the rhizomes, continuing its perennial life cycle.
PropogationPropogation time
Early spring
Anemone × hybrida 'Whirlwind', commonly known as the Japanese anemone, is primarily propagated through division in the spring. This involves carefully lifting the plant from the ground as the new growth emerges. The clump should be gently separated into smaller sections, each with several shoots and a portion of the root system. These divisions can then be replanted immediately in well-prepared soil, spacing them about 18 inches (approximately 45 centimeters) apart to allow ample room for growth. Water the new plants thoroughly to establish them. This is the most popular method and is usually successful as it allows the perennial nature of the plant to thrive in new locations.
