Culture
Easily grown in evenly moist, organically rich, well-drained soils in part shade to full shade. Best in part shade (some morning sun or sun dappled conditions). Established plants have some tolerance for dry shade (particularly plants with thick leaves), but soils should never be allowed to dry out. Full size and quality form are best achieved with consistent moisture. Water is best applied directly to the soil beneath the leaves. Divide plants as needed in spring or autumn. Division is usually easiest in early spring before the leaves unfurl. Plant in locations protected from wind. Hostas are generally considered to be low-maintenance perennials.
Noteworthy Characteristics
Hosta is a genus of about 70 species of shade-loving, rhizomatous, clump-forming, herbaceous perennials which are native to open woodlands, woodland margins and glades in Japan, Korea, China and eastern Russia. Hostas are primarily grown for their ornamental foliage. Stalked, conspicuously-veined, often dense, basal leaves in a variety of shapes, sizes, colors and textures rise up from a central rhizomatous crown to form a rounded to spreading mound of foliage. Bell or funnel-shaped flowers in terminal, mostly one-sided racemes bloom in late spring or summer atop vertical, unbranched, usually leafless but frequently bracted scapes which rise upward from the crown or rootstock to a point often well above the foliage mound.
Genus name honors Austrian botanist Nicholas Thomas Host (1761-1834) and was first established in 1812. The genus was subsequently renamed in 1817 as Funkia in honor of botanist Heinrich Christian Funk under the belief at that time that Hosta was an invalid name. Hosta was finally reinstated as the genus name in 1905 by the International Botanical Congress.
Funkia remains a popular common name today in some areas. An additional common name for plants in this genus is plantain lily (foliage is somewhat plantain-like and flowers are somewhat lily-like in some species).
'High Society' is a small, clump-forming hosta (sport of H. 'June') that typically grows in a foliage mound to 8" tall spreading to 15-18" wide. Prominently-veined (11 pairs), broad-ovate leaves (5" long and 4" wide) with heart-shaped lobes and cuspidate tips emerge in spring with creamy yellow centers surrounded by wide, sharply contrasting, blue green margins (2/3 of leaf area). Yellow centers usually mature to white in summer. Bell-shaped pinkish-white flowers bloom late summer to early fall (August-September) on leafy upright scapes rising above the foliage mound to 9-11" tall. H. Hansen and Shady Oaks Nursery 2004. U. S.

Problems
Slugs and snails are attracted to the foliage, chewing jagged holes in the leaves, and if left unchecked, can cause serious damage over a fairly short period of time. Watch for foliar nematodes which feed on the leaves causing interveinal browning. Leaf spots and crown rot are less frequent problems. Plants infected with Hosta Virus X (HVX), tobacco rattle virus, or tomato ring spot virus should be immediately removed from garden areas and destroyed. Leaves, particularly of exposed plants, can be severely damaged by hail storms. Leaves are commonly eaten, often voraciously, by deer and rabbits.
Uses
Hostas are a mainstay of shade gardens. Notwithstanding the often showy flowers produced, hostas are primarily grown in shady areas for the ornamental excellence of their foliage. Very effective in groups or massed. Good background plant. Shady borders, shade gardens or woodland gardens.
