Hostas are easy to grow, shade-loving plants. In shade gardens, several varieties of this low-growing plant may be grouped together, or a single species may be used as a border. Hostas are grown for their foliage and typically are classified by their leaf size and appearance. While the leaves are generally green, some species have an almost blue color, while others are variegated with yellow or even white stripes.
The American Hosta Grower’s Association selected the earth angel as its 2009 hosta of the year. The earth angel is classified as a giant hosta because of its leaf size. The variegated leaves have a wide blue-green band in the center and creamy yellow-to-white stripes covering the leaf boarder. In June, lavender lily-like flowers emerge. For more impressive foliage, keep these flowers cut back. Clumps may easily be divided in the spring or fall. The earth angel will tolerate partial sun and prefers normal-to-sandy or clay-like soil of any pH. This plant is resistant to rabbits but will not tolerate deer.
The August moon is a hosta that will tolerate full sun. This makes it a good choice for the borders of shade gardens, where there would be more sun than most hostas will tolerate. This hosta is characterized by heart-shaped gold leaves that are uniformly crinkled. As summer progresses, the leaves change from a green-gold to a harvest-gold color. This hosta may produce flowers that are pale lavender in color anywhere from mid-July to mid-August.
The blue cadet is a smaller hosta that is perfect for tight spaces, small gardens or containers. This hosta forms small, compact mounds of rounded blue-green leaves. Although this hosta will produce spectacular foliage in all types of sun, it prefers shade. Because of its sun-tolerant nature and small stature, the blue cadet makes a good choice for borders and edging plants. This hosta is attractive when planted in clumps; however, each plant should be spaced at least 14 inches apart.
The leaves of the Krossa regal are unlike any other hosta, because they grow erect instead of in a mound. With a potential size of 6 feet wide and 36 inches tall, Krossa regal makes a noticeable addition to any garden. This hosta, which was imported from Japan in the 1950s, has leathery blue-green leaves that are slug-resistant. Because of its pest-resistant properties, it is one of the most widely planted blue-green hostas on the market.
