It's easy to see why hostas are favorite perennials for woodland and shaded gardens. These perennials come in a wide variety of sizes, leaf shapes, colors and textures. Choosing hostas with variegated or golden green foliage is a great way to lighten a shady spot in the garden. These versatile perennials also make great ground cover. Hostas are easy to grow and do best when planted in shade or partially shaded areas. Most varieties bloom in the summertime, bringing arching sprays of bell-shaped blooms. The foliage, though, is what most gardeners seek in hostas.
