Acanthus mollis ‘Whitewater’

Leaves with white shades look like waves of clean, clear water. Pink and cream flower stalks are showy and last throughout the entire summer. Make a statement in the border or shade garden with this bold selection. Winter hardy to USDA Zones 7-10 where it is easily grown in average, fertile, medium moisture, well-drained soils in full sun to part shade. Plants tolerate a wide range of soils except poorly-drained ones. Plants may not flower well in too much shade. Late spring frosts can impair or eliminate flowering for the year. Remove flowering stalks after bloom. In cold winter areas, plant foliage should be left in place over winter but removed in early spring as new foliage appears. Plants can spread aggressively by creeping rootstocks, particularly in loose soils. Unwanted spread can be addressed by root barriers. Plants generally spread less in the northern parts of their growing range.  (Courtesy of Missouri Botanical Gardens Plant Finder)
