Overview
Registered in 2009, *Hosta* 'World Class' is a medium-sized cultivar of unknown pollen parentage, with *H.* 'Gaijin' as the pod parent. Its distinctive heart-shaped, deeply cupped leaves in medium blue-green, combined with moderate corrugation and a slightly shiny upper surface, create a notably textured and colored mound.
In the Garden
This cultivar forms a moderate-growing, mound-like clump reaching 36 inches (91.4 cm) in diameter and 14 inches (35.6 cm) in height. It performs best in partial to full shade, typical of most hostas, where its blue-green foliage retains color. The substantial leaf texture pairs well with fine-leaved perennials such as ferns or *Heuchera*, and its medium size suits border middles or woodland garden settings.
Care Notes
Water regularly to maintain consistent moisture, especially during dry periods. Apply a balanced, slow-release fertilizer in early spring as new growth emerges. While slug resistance is not documented, the moderately corrugated and cupped leaves may offer some protection; standard slug control measures are advisable in damp conditions. Deer may browse the foliage.
