Hosta Formal Attire develops into a substantial mound, reaching a height of 60cm-75cm and spreading up to 150cm at maturity. This variety is notable for its refined appearance. The large leaves exhibit a pleasing crinkly texture and have wide margins that transition from cream to white over time. It forms a relatively open and broad clump. For optimal growth, it is recommended to place it in partial shade, either in a sizable pot or directly in the ground. During July and August, pale lavender flowers bloom on scapes that reach 100cm in height. This plant is resistant to slugs and can tolerate a little sunlight.
