Grow in moist, fertile, well-drained soils in full sun to part shade. Prefers full sun, but appreciates some part afternoon shade in hot summer climates. Best foliage color occurs in cool summer climates north of USDA Zone 7. Thrives in consistently moist soils, but tolerates somewhat drier soils better than many other willows. Prune as needed in late winter to early spring. Many gardeners prune stems back in late winter each year to encourage more vigorous growth and to control plant size.
