Best grown in moist, rich, humusy, medium to wet soils in full sun to part shade. Best in cool summer climates in part shade areas. Tolerates close to full shade. Consider pinching back the stem ends in spring to reduce mature plant height, especially if growing plants in strongly shaded areas where they are more likely to need some support. In optimum environments, however, staking is usually not required. Appreciates a good composted leaf mulch, particularly in full sun areas. Spreads slowly by rhizomes to form large clumps, but is not invasive.
Light Requirements: Part Sun / Part Shade
Mature Height: 24"
