How to Grow Anemone — Windflower

Anemone–commonly called windflower–is an upright perennial with divided, dark green basal leaves. Windflowers produce large daisy-like flowers, some double, from late summer to early fall. Windflowers arise from corms and are slow spreading.

Anemone is suitable for the border, wild garden, or rock garden. The most popular types are the autumn-flowering, fibrous-rooted Japanese Anemone, and there are spring-flowering, tuberous-rooted Poppy Anemone.

Anemones are beautiful in the border when naturalized, the graceful flowers on slender stems rising above sturdy clumps of good-sized leaves. They should be planted in moist soil, rich in hums in a rather shaded portion of the border.

Never allow Anemone to dry out in summer; frequent watering and a mulch of decayed leaves will increase the beauty of the flowers. The clumps with their fibrous roots may be increased by division in spring, although plants resent disturbance.

When to Plant Anemone

  • Anemones are grown from tubers or seeds.
  • Plant tubers 3 to 4 inches (7.6-10cm) deep in Zones 4 to 5 in spring a few weeks before the last frost. In Zones 6-9, plant tubers in late autumn.
  • Soak tubers in water overnight before planting.
  • Start seeds indoors 3 to 4 weeks before the last frost in spring.
  • Start seeds outdoors in spring after all danger of frost is past; germination is irregular; some seeds may not germinate the first year.
  • Plant tubers outdoors in spring after the last frost.
  • Set container-grown plants outdoors after the threat of frost has passed; harden off plants before setting them in the garden.

Planting and Spacing Anemone

  • Cover Anemone seeds planted indoors or outdoors with not more than 1/8 inch of soil; germination will occur in 5 to 6 weeks at 60°F (15.6°C).
  • Plant tubers outdoors after soaking them overnight in water; plant tubers in spring after all danger of heavy frost passes. Plant tubers 3 inches (7.6cm) deep.
  • Space Anemones 6 to 36 inches (15-91cm) apart depending on the variety.

How to Water and Feed Anemone

  • Anemones need ample water; keep the soil evenly moist.
  • Fertilize Anemones at planting time. Side-dress plant with a light sprinkling of all-purpose flower fertilizer; do not over-fertilize; too much nitrogen will burn plants.

Anemone Care

  • Mulch around Anemones to conserve soil moisture.
  • Remove faded flowers and yellowed leave; cut off stems of fall-blooming anemones after flowering time is finished.
  • Anemone coronaria tubers should be lifted in the fall and dried and stored indoors. Lift tubers after the leaves turn yellow. Replant the tubers in spring.
