Royal standard hosta is an old standard that first appeared in garden centers in the mid 1960s. This clump forming, shade tolerant, herbaceous perennial is primarily grown for its ornamental foliage. In late spring, it produces a large clump of heart-shaped, bright green leaves, and in early to midsummer upright stems of white, trumpet-shaped flowers appear. This hosta prefers part sun to part shade and fertile, well drained soil. It is widely used in mixed perennial borders or planted in masses as a groundcover for shade. Most plantain lilies are highly susceptible to slug damage.
