About
Hosta sieboldiana, Siebold's plantain lily, is a large, clump-forming Hosta with broad, ovate, blue-green leaves with prominent, deeply impressed veining and a wavy edge. White, bell-shaped flowers on stems to 80 cm appear during summer. One of the most stately and architectural of all hostas for a shaded border or woodland garden.
About the genus
Hosta, the plantain lilies, are clump-forming herbaceous perennials with simple, ovate or lance-shaped leaves, often attractively coloured or variegated, and erect racemes of nodding, funnel or bell-shaped flowers in early summer. Valued primarily for their foliage, they are excellent shade-tolerant border and container plants.
