Overview

Hosta tokudama is a clump-forming, mounded perennial in the genus Hosta, part of the Asparagaceae family, with deciduous; broad, ribbed or puckered, often variegated or glaucous foliage. Hosta tokudama grows best in partial to full shade; blue-leaved kinds hold their colour best out of sun, and tolerates fertile loam enriched with organic matter soils and neutral to slightly acid pH. Its UK hardiness is rated H7. It is native to Japan.

About

Hosta tokudama is a clump-forming, mounded perennial noted for broad, ribbed or puckered leaves that are often variegated or carry a glaucous (blue-green) bloom. Native to Japan and a member of the Asparagaceae, it flowers in summer. It prefers partial to full shade and holds a blue leaf tone best out of direct sun. Plants favour fertile, organic loam kept reliably moist but never waterlogged and are fully hardy in the UK (H7).

About the genus

Hosta is a genus of plants commonly known as hostas, plantain lilies and occasionally by the Japanese name gibōshi. Hostas are widely cultivated as shade-tolerant foliage plants. The genus is placed in the family Asparagaceae, subfamily Agavoideae, and is native to northeast Asia.

In the garden

Hosta tokudama originates from Japan and belongs to the genus Hosta within the Asparagaceae. It forms neat mounds of broad, ribbed or puckered leaves, many cultivars showing variegation or a glaucous, blue-green cast. Flowering occurs from June to August, when upright scapes rise above the foliage. Position the plant in partial to full shade; blue-leaved selections retain their tone most strongly away from direct sun. Choose a north- or east-facing aspect in a sheltered spot and work plenty of organic matter into a fertile loam. The soil should be neutral to slightly acidic and kept reliably moist without becoming waterlogged. Hosta tokudama is rated H7 for UK hardiness and corresponds roughly to USDA zones 3–9, so it withstands typical British winters when planted in a protected site. Use it in shaded borders or beds where its low, mounded leaf habit forms a textural ground-layer; place it where moisture can be maintained but drainage prevents standing water. The summer flower scapes add vertical contrast between June and August, particularly against darker-leaved companions.

Care notes

Pruning and caring for Hosta tokudama

Cultivation
Give a cool root run, generous leaf mould and consistent moisture — drought is what produces thin, scorched leaves. Growing in containers makes slug control far easier, and a top-dressing of grit or a copper band around the pot helps further.
Pruning
No pruning needed. Remove flower scapes once faded if seed is not wanted, and clear collapsed foliage in late autumn to take away slug shelter.
Propagation
Divide crowns in early spring as the shoots emerge, cutting between the buds with a sharp knife. Division is the only way to keep a named cultivar true.
Pest resistance
Highly attractive to slugs and snails, which is the one real limiting factor; vine weevil can be serious in containers.
Disease resistance
Generally healthy. Hosta virus X is the notable exception — affected plants should be destroyed rather than divided.
