  form2 form Form

-small herbaceous perennial

foliage2 foliage Foliage

-alternate, silvery-green tomentose leaves arise from short stems, and are twice palmately divided into linear segments of extremely fine foliage texture

-autumn color remains silvery, until quickly dying back to the crown with the initial frosts

Flowers
flowers

-inflorescences are silver in bud and yellow-white in flower, are small, sparse to non-existent, may be unnoticed above the silver foliage, are ornamentally insignificant, and bloom in Aug. (if at all)

Culture

-full sun to partial sun

-placement in moist, well-drained, relatively infertile soils in full sun prevents excessive vertical vegetative growth, which will usually keep the center of the foliage mound from unattractively opening up and separating by mid-summer

-if placed in fertile soils, the foliage may grow from 1-1.5' tall; in this case, clump splitting can be prevented or delayed by shearing the foliage back halfway in July, before flowering begins

-tolerant of poor soils, dry soils, heat, and drought

-propagated by crown division or by rooted stem cuttings

-Daisy Family, with stem rot or foliage rust under humid conditions being the 2 primary disease problems, and with no significant pest problems

-moderately available in containers

Hardiness

-zones 3 to 7

Origin

-native to Japan

Assets

-silver-colored, fine-textured foliage in a spreading mound form

-works well as a neutral spacer or framing plant, in combination with perennials whose flowers are mostly in the cool color range (pink, lavender, blue, purple, and even scarlet to maroon)

-fairly drought tolerant

Liabilities

-foliage often splits apart in the center of the clump by mid-summer for mature-size clumps

-foliage may rot or rust under high humidity conditions

Function

-edging, specimen, border, mass planting, rock garden, or focal point mounding perennial

Texture

-very fine texture

-thick density
