Best grown in organically rich, medium to wet soils in full sun to part shade. Tolerant of a wide range of soils, including swampy or boggy conditions. Prefers consistently moist, well-drained soils. Best red stem color occurs on young stems. Although pruning is not required, many gardeners choose to remove 20-25% of the oldest stems in early spring of each year to stimulate growth of new stems which will display the best color. As an alternative to annual pruning, some gardeners prune all stems close to the ground in early spring every 2-3 years to renew.
