Botanical Name

Plant Common Name

Hosta, Iona Plantain Lily, Plantain Lily

General Description

Hostas are herbaceous perennials grown for their leaves, toughness, tolerance for shade, and mounding habit. This one, the pretty variegated ‘Iona,’ is a medium-sized hosta that forms neat mounds of heart-shaped leaves tapered to a point, puckered and lightly corrugated. They are gray-green with irregular, narrow creamy-white margins. Lavender bell-to-funnel-shaped flowers appear on leafless stems held above the foliage in summer.

Like most hostas, ‘Iona’ grows best in full to partial shade and tolerates a wide range of fertile well-drained soils. It prefers average, even moisture. In hot, dry conditions the white margins may wither. A site with no direct mid-day sun can help. Use ‘Iona’ for contrasts of size, texture and color in shaded perennial gardens and woodlands, or massed under large trees as a groundcover.
