Hosta Undulata Albomarginata forms a broad, mound-shaped clump of dark to medium green leaves outlined by irregular cream margins. The basal leaves are broadly oval, lightly wavy at the edge and marked by parallel veins. Upright scapes carry loose clusters of pale lavender, funnel-shaped flowers above the foliage in midsummer. The cream-edged leaves brighten shaded ground and make the plant useful for border fronts, woodland-style planting, containers and underplanting beneath shrubs.
Grow it in partial or full shade in fertile clay or loam that stays moist but drains freely. A north- or east-facing, sheltered position helps protect the leaves from cold, dry winds. Water before the soil dries, especially while new growth is expanding, and apply a light fertilizer around emerging growth in spring. Divide established clumps in early spring or late summer. Remove dead leaves after seasonal dieback, watch for slugs and snails, and keep pets and grazing animals from eating the foliage.
