Hostas are extremely popular, hardy herbaceous perennials grown primarily for their beautiful foliage. They are easy to grow, shade-tolerant plants. Leaves come in a wide range of shapes, colors, sizes, and textures and may be solid in color or variegated in different combinations of blue, green, white, and gold. The plants are low maintenance. The blue color is actually a green leaf coated with a wax that makes it appear blue. The wax tends to "melt" from the leaf following exposure to sun and the heat of summer.
Hostas are considered shade-tolerant plants, but most do not thrive if grown in deep shade. Hostas grow best in an exposure with morning sun and afternoon shade. Some cultivars will tolerate some afternoon sun, although plants grown in full afternoon sun (especially variegated plants) will show signs of marginal burning on leaves in the summer months.
In general, the blue-leafed hostas require shade.
