Best grown in medium moisture, well-drained soil in full sun to part shade. Prefers consistently moist soils that do not dry out, but drainage must be good. Will freely self-seed in optimum growing conditions. Plantings may be sheared back after bloom to avoid any unwanted self-seeding and/or to tidy foliage for remaining part of the growing season. Plants may need to be divided every 2-3 years to keep plantings vigorous.
‘Lucerne’ reportedly does not vigorously self-seed as species plants often do. (Courtesy of Missouri Botanical Garden Plant Finder)
