description_en: Genus of about 70 species of mostly clump-forming, occasionally rhizomatous or stoloniferous perennials from sun-baked volcanic cliffs, rocky streamsides, woodland, and alpine meadows in China, Korea, Japan, and E. Russia. Numerous hybrids have also been raised, mainly in the USA. Hostas are grown primarily for their bold foliage, produced in dense mounds of overlapping, ovate to heart-shaped or lance-shaped leaves (see panel below). The leaves may be green, yellow, grey-blue, or variegated, and are often glaucous. One-sided racemes ofbell- or funnel-shaped flowers, to 3cm (1 1/4in) long, are borne on usually leafless, some-times leafy scapes, mainly in summer. They are followed by oblong, green, later pale brown seed capsules. Plant heights given in the descriptions below refer to the mounds of foliage, flower (scape) heights are given separately. Hostas may be grown as ground cover under deep-rooted, deciduous trees, in a mixed or herbaceous border, or near water. Smaller hostas are excellent for a rock garden, a peat bed, or containers.

hardiness_en: Fully hardy.

cultivation_en:

propagation_en: Although easily raised from seed sown in containers in a cold frame in spring, only seedlings of H. ventricosa will come reliably true in cultivation. Divide in late summer or early spring. Many new hostas are propagated through tissue culture.

pests_en: Particularly susceptible to damage from slugs and snails. Container-grown plants are vulnerable to vine weevil. Virus infecdtions may also be a problem.
