Blue hostas create a cooling effect in the shade garden. Blue colored hostas can range in color from a powder blue to a deep dark blue. A waxy coating on the hosta leaves is what gives them this blue color. Excessive heat, rain, irrigation tend to melt the waxy coating off of the hosta leaves. More shade is required for these beauties than other varieties so give them early morning sun and avoid any mid-day and afternoon sun. Here at Pine Forest Gardens we like to plant large blue hostas and contrast them with bright gold or variegated hostas. In contrast we also offer miniature blue hostas as well as small, medium and giant blue hostas.
