(ah-ne-mo' nee)

Common name:Windflower

Family: Ranunculaceae, Buttercup

Height x width, habit: 6-48" x 6-36" (varies with species), low mounded with flowers above

Growth rate:moderate to fast

Foliage: compound into 3 segments (ternate to trifoliate), mostly or all basal depending on species

Flowers: often resembling a poppy, many colors depending on species, 2-3" across, most species have no petal rather showy sepals

Hardiness: 3-5 to 7

Soil: well-drained, fertile, organic, moist

Light: sun to part shade

Pests and Problems: leaf spots, rhizome rot, rusts, viruses, botrytis blight, powdery and downy mildew, smut, flea beetles on seedlings, nematodes (pests seldom serious)

Landscape habit, uses: borders, naturalized woodlands, rock gardens for low species

Other interest: ancient name from the Greek anemos for wind, a name used by Theophrastus

Other culture: often do best protected from wind; tuberous rhizomes should be planted out in fall in south, in spring in north after soaking overnight in water; treat as gladiolus, digging tubers and bringing indoors, in zones 3-4

Propagation: seed, division of tubers in fall, root cuttings of x hybrida and similar

Species:

The following species and cultivars are most commonly found in U.S. commerce. Those marked * are the most popular. Colors are for the species, some of which have other colors for cultivars. Three general groupings occur according to ecological habitat.

• Fall blooming fibrous-rooted occur in moist open meadows or open damp woodlands.

• Those with tubers or rhizomes vary in bloom time, and occur in several habitats including woodlands and well-drained soils, although they tolerate drier soils during summer dormancy after bloom.

• Tuberous-rooted species flower early and occur in areas of hot dry summers and light sandy soils; they require dry dormancy after flowering and are often less hardy.

Additional species notes:

• blanda (blan' dah)--Grecian Windflower, good for naturalizing, mainly found as cultivars

• canadensis (ca-na-den' sis)--Meadow Anemone, very invasive

• coronaria (cor-o-nair' ee-ah)--Poppy Anemone, mainly found as cultivars, short-lived so should be treated as annuals, good cut

• x hybrida (hi-bri-dah')--Hybrid/Japanese Anemone, many good hybrid cultivars

• hupehensis (hue-pe-hen' sis)--Japanese Anemone, found originally in Japan in 1695 and brought to England in 1844 by Robert Fortune, it was originally called A. japonica; many good cultivars now in var. japonica of this species

• nemorosa (nee-more-o' sah)--Wood Anemone, prefers slightly acid soil and fall planting, variable with many cultivars

• sylvestris (sil-ves' triss)--Snowdrop Anemone, very invasive especially in cooler North

• tomentosa (toe-men-toe' sah)--Grapeleaf Anemone, forming clumps and spreading by stolons, very easy to grow, attractive for early fall, formerly known as vitifolia only more hairy (tomentose) than that species
