Hosta Prairie Sky will develop into a compact mound of approximately 36cm to 40cm in height, with a spread reaching up to 90cm at maturity. This variety features thick, rounded, nearly heart-shaped, slightly cupped, powder blue leaves that retain their colour exceptionally well, even under extreme heat conditions. However, it is advisable to position the plant in a shaded area to preserve its vibrant blue hue. This Hosta is regarded as one of the finest blue varieties introduced to date. The robust leaves contribute to its resistance to slugs. Pale lavender flowers emerge from July to August on scapes that can grow up to 80cm tall. This is an excellent choice for those seeking a medium-sized blue Hosta that requires minimal maintenance.
