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

-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
