Two beautiful hostas that work well together are Prairie Moon and Prairie Sky.
The distinctly yellow leaves of Prairie Moon holds for most of the season. The wedged shaped leaves are slightly wavy and are held on by red-flecked petioles. Best planted in part shade, light lavender flowers appear mid-summer.
One of the best blue hostas is Prairie Sky. Showy blue color all season – thick substance and lightly cupped leaves – makes this one a real winner. Prairie Sky will offer light lavender flowers also.
Both these plants are medium sized hosta – 16″ to 24″. Try pairing these with some heucheras – both the purple and yellow varieties.
