Variegated cultivars are not as hardy. Shear off flower stalks. Full sun and dry conditions. Likes areas of high to medium moisture levels but does well in dry shade under trees. Best grown in groups.
Slugs can be a problem.
Needs good winter protection. Somewhat less vigorous than green form but more attractive. Highly competitive and deeply rooted. Grows in almost any type of soil and light condition. Foliage may scorch in full sun.
