Anemone (De Caen)

Anemone coronaria corms are small, hard, and irregularly shaped, making it difficult to tell top from bottom. Soak them in room-temperature water for 4-6 hours before planting to rehydrate them and encourage sprouting. Plant 2 inches deep and 4-6 inches apart. If unsure of orientation, plant on their side—the shoots will find their way up.

In mild climates (zones 7-10), plant corms in autumn for spring blooms. In colder areas, plant in late winter or early spring as soon as the soil can be worked, or start indoors in pots. Anemones prefer cool growing conditions and will flower prolifically when temperatures are between 50-65°F (10-18°C).

Provide consistent moisture during growth and flowering, but ensure soil drains well to prevent corm rot. Remove spent flowers regularly to encourage continued blooming. After flowering, allow foliage to die back naturally. In zones 6 and colder, apply a thick mulch layer for winter protection or lift corms and store indoors.

Anemone blanda, commonly known as the Grecian windflower, is a tuberous perennial native to southeastern Europe and western Turkey. Its natural range extends across Greece, the Balkans, and the mountainous regions of Anatolia, where it thrives in rocky, well-drained soils beneath deciduous oak and beech forests at elevations between 1,500 and 5,000 feet. The species was first formally described by the German-Swiss botanist Augustin Pyramus de Candolle in 1818 and introduced to Western European gardens in the mid-nineteenth century. Early Victorian plant collectors were captivated by its delicate, daisy-like flowers and its ability to naturalize in temperate climates far removed from its Mediterranean homeland. By the early twentieth century, Dutch bulb growers had begun commercial production of selected color forms, most notably the deep blue 'Atrocaerulea' and the pure white 'White Splendour,' both of which remain widely available today. The common name windflower reflects the Greek root anemos, meaning wind, a reference either to the breezy hillside habitats where the plant grows wild or to the ancient belief that the flowers opened only when the spring wind blew. In Greek mythology, anemones were said to have sprung from the blood or tears shed over the dying Adonis, linking the flower to themes of love, loss, and renewal. Anemone blanda belongs to the buttercup family Ranunculaceae and is closely related to the wood anemone (Anemone nemorosa) of northern Europe. Unlike its woodland cousin, A. blanda prefers sunnier, drier conditions and is better suited to rock gardens, raised beds, and the edges of gravel paths. Today it is cultivated worldwide in USDA hardiness zones 4 through 8 and is valued for its early spring color, low maintenance requirements, and ability to establish permanent self-sustaining colonies with minimal care.

Anemone coronaria requires well-drained, humus-rich soil with a pH of 6.0-7.0. Heavy clay must be amended with compost and perlite or coarse sand. Work a balanced slow-release fertilizer into the soil at planting time. During active growth, feed every two weeks with a half-strength liquid fertilizer. Avoid excess nitrogen, which promotes foliage at the expense of flowers.

Cut anemone flowers when buds show full color but before they are completely open—they will continue to open in the vase. Cut in the early morning with stems as long as possible. Anemones are excellent cut flowers, lasting 5-7 days in fresh water. Re-cut stems and change water every other day for maximum longevity. The flowers close at night and in dim conditions, then reopen in bright light, creating a charming living arrangement.

In zones 7-10, corms can remain in the ground year-round with well-drained soil. In colder zones, dig corms after foliage dies back, brush off soil, and dry in a warm, ventilated area for a week. Store in paper bags with dry vermiculite at 55-65°F (13-18°C). Re-soak before replanting. Corms left in wet winter soil will rot. In marginally hardy areas, a 4-inch mulch layer of straw may provide sufficient protection.
