Hosta is a genus of hardy herbaceous perennial plants commonly grown as shade-tolerant ornamentals for their foliage. Native to eastern Asia, the genus is placed in the asparagus family (Asparagaceae) and includes species and many cultivars known as hostas or plantain lilies.

Taxonomy and naming

Hosta is a genus in the family Asparagaceae, subfamily Agavoideae. It is also known by the common name plantain lily, and the Japanese name gibōshi is sometimes used.

Description

Hostas are clump-forming herbaceous perennials with ribbed, basal leaves and summer flowers on upright stalks. Leaf size, colour, and variegation vary widely among species and cultivars.

Distribution and habitat

The genus is native to eastern Asia, including China, Japan, Korea, and the Russian Far East. In cultivation, hostas are commonly planted in shaded or partially shaded garden settings.

Cultivation and horticulture

Hostas are popular ornamental plants because they are hardy, long-lived, and easy to grow in many temperate gardens. Breeders have produced thousands of cultivars with diverse foliage forms and colours.

Key facts

  • Hostas are grown primarily for their leaves, which may be green, yellow, blue, or variegated.
  • The genus is native to eastern Asia, especially China, Japan, Korea, and the Russian Far East.
  • Hostas are widely used in shade gardens and tolerate a range of growing conditions.
  • Flowers are usually borne on stalks above the foliage and are less prominent than the leaves.
  • The genus has many cultivars, reflecting long-term horticultural breeding and selection.
