Considered by many as one of the best blue Hostas available, Big Daddy Hosta forms a large mound of thick, chalky blue leaves that are cupped and puckered. Its thick leaves have good slug resistance. White flowers in the shape of bells appear in late summer. Hostas are excellent perennials for shade that require minimal care. They are lovely massed in woodland settings or used as specimens. With their weed smothering foliage, they make idea ground covers. Although they are tough plants that can withstand periods of drought, for best results keep well watered during dry spells.
