Plant Anemone blanda 'blue shades' in fall for spring blooms.

Vibrant, versatile anemones brighten gardens from spring all the way into fall. There are about 200 species of these charming members of the buttercup family (Ranunculaceae) in many colors, heights and flower forms, and they bloom in different seasons.

Native to Asia, Europe and North America, anemones have had different meanings over time. Middle Age peasants wore them for protection. To Victorians, an anemone flower indicated frailty. Today, a white anemone flower symbolizes sincerity while a red anemone means forsaken love. These nearly carefree beauties take their name from anemos, the Greek word for "wind."

About Anemones

Botanical Name: Anemone
Common Name: Windflower, Grecian windflower
Hardiness Zones: 3 to 10, depending on the species
Bloom Time: spring, summer, fall

When To Plant Anemones

Knowing when anemones bloom determines when to plant them. Most fall into three groups: spring flowering, spring and summer flowering or fall flowering. Plant spring bloomers in the fall at the same time you'd plant daffodils or tulips. Plant fall bloomers in springtime after your last frost.

Most anemones grow from bare roots or corms that look like bulbs. Flowers can be single, double or semi-doubles. Some anemone plants are considered invasive or aggressive, so if you're unsure about the ones you want to grow, ask your local extension service agent for advice.

Japanese anemones (A. hupenhensis var. japonica, often shown simply as A. hupenhensis) and hybrids related to them bloom in late summer and fall and range from 12 to 24 inches tall. Most need four to six hours of daily sun and are hardy in USDA Gardening Zones 4 to 8. They come in pink, mauve or white; each flower has a ring of yellow stamens in the center. Japanese anemones are great for cutting.

Planting Anemones

Before you plant anemone corms, soak the corms for a few hours in lukewarm water to plump them up. Then plant them 2 to 3 inches deep and 3 to 4 inches apart, or as directed on their tags or labels. Place small corms closer together and in groups for a better show. It doesn't matter which end faces up.

Snowdrop anemone (Anemone sylvestris) blooms profusely, so it's a good choice for naturalized areas.

Plant other types of anemones 3 to 6 inches deep. If you're planting anemones that came in nursery pots, plant them at the same depth they were already growing. Japanese anemones can reach 4 feet high, so space them 1 to 2 feet apart. Mix some bone meal into the soil when you backfill the holes and water gently.

How to Grow Anemones in Containers

Most anemones do best in the ground, but A. coronaria types like De Caen and St. Brigid can be grown indoors. Use large pots with drainage holes and well-draining potting soil. Plant corms four inches apart. Use one bare root plant per pot.

If you're growing a species that's hardy in your zone (and your pot is crack- and freeze-resistant), mulch the top of the soil and leave the pot outside to overwinter (some species require a period of winter chill to bloom). Otherwise, keep the pot in an unheated garage or another area where the temperature stays between 40 and 50 degrees. Move it outside after the temperatures are consistently above freezing. If shoots emerge while the pot is indoors, move it into a brightly lit spot.

How to Grow Anemone Flowers

Light Needs

Most anemones need at least six hours of full sun each day, while others can tolerate partial shade with at least four hours of direct sun each day. Research the type of anemone you're growing so you'll know where to plant it.

Soil

While anemones aren't picky about pH, they prefer acidic to neutral soils. Give them well-drained soil enriched with compost or organic matter.

How to Water

Apply an inch of water each week if rainfall is insufficient. Aim for consistently moist soil that's never soggy. Avoid splashing the foliage to help prevent diseases.

Fertilizer Needs

If you added bone meal to the soil at planting, you don't need additional fertilizer.

Temperature

Most anemones prefer cool weather, but even plants that are winter hardy in your zone do better with some mulch for insulation.

Toxicity

Anemones are toxic to people and pets.

How to Prune Anemones

Pruning isn't necessary, but you can remove dead foliage after the first fall frost to tidy up your garden. Most foliage on spring bloomers dies back unobtrusively.

Anemone Pests and Diseases

Fungal diseases like powdery mildew don't usually kill anemones but can be managed with a horticultural oil labeled for your specific disease problem.

Japanese beetles and black blister beetles that attack anemones can be treated with horticultural oils or insecticidal soaps. For foliar nematode damage, which causes discolored blotches on leaves, remove and destroy infected plants. Pick off slugs and snails or set out small saucers of beer so they'll crawl in and drown. Commercial baits are available but may harm other garden wildlife. Deer and rodents usually leave anemones alone.

How to Propagate Anemones

The best way to propagate anemones is by division. In the fall, dig up corm-type anemones and break off the smaller attached corms. Replant the original and the small ones or store them in a cool, dry location until the following spring.

Dig up other types of anemones in the fall, shake off the dirt and cut their tuberous roots or rhizomes into 3- to 6-inch sections, leaving a nodule on each one. Replant them or store them in a cool, dry place for the winter.

Types of Anemone Plants
