Anemone blanda, also known as Grecian windflowers, are delicate blooms resembling daisies that grow from tubers in hues of pink, blue and white. Low growing and bunchy, these clusters of blooms have the qualities of perennial flowering plants as well as the benefit of overwintering naturally in USDA Hardiness Zones 8 to 9.
Choose a sunny location for planting windflower tubers that has excellent drainage. Fall is the right time for planting, prior to the first frost.
Prepare the planting bed by incorporating up to 2 inches of organic matter, such as composted pine bark, into the soil to a depth of 10 inches.
Mix a 10-10-10 soluble fertilizer at the manufacturer's suggested rate into the prepared soil.
Incorporate 2 cups of bonemeal into the soil per 10 square foot area of planting bed.
Soak the tubers in water overnight to encourage sprouting.
Plant the tuber up to three times as deep as the tuber is tall. Allow an inch between tubers for small specimens, and 3 inches for larger ones.
Cover the planting bed with 2-inch layer of organic mulch, such as composted pine needles.
Water the bulbs at planting if rainfall is not adequate to moisten the soil. Avoid over watering in the fall, as bulb rot may ensue. Provide up to 1 inch of water weekly in spring once the windflower stalks emerge in the absence of rainfall.
Let the foliage die back naturally once the blooms are spent. The foliage feeds the bulb for next year's bloom, so mowing it prematurely reduces or eliminates future flowers.
Dig the tubers in USDA Hardiness Zone 8 or colder for storage. Brush off the dirt and pack in peat moss in a container with good air circulation. Store the tubers in a cool, dry area for winter.
