Pests or Diseases: Deer-resistant. No serious insect or disease problems. Young shoots are susceptible to snail damage. Foliage often sprawls in an unattractive manner by mid-summer.
Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Grow in average, medium to wet, well drained soil in full sun to part shade. Prefers moist, acidic, humusy soils. Tolerant of boggy soils. Divide clumps when they become overcrowded. Foliage declines after flowering and should then be cut back almost to the ground to encourage new growth and a possible fall bloom.
