| Year registered | 1983 |
|---|---|
| Registrant | S. Moldovan |
| Section class | I-2 (Giant) |
Overview
Registered in 1983 by S. Moldovan, this giant blue-green cultivar resulted from a cross using *Hosta* 'Elegans' as the pod parent. It is visually distinctive for its exceptionally large, heavily textured leaves with silvery blue, ruffled margins and a broad, rounded form.
In the Garden
'Hosta 'Sumi' reaches a mature spread of 54 inches (137 cm) and a height of 36 inches (91 cm), making it suitable as a bold specimen or background plant in shaded borders. It performs best in partial to full shade, where its blue-green foliage retains color without scorching. Pair with ferns, astilbes, or other shade-tolerant perennials that contrast with its broad leaves; it is too large for container cultivation.
Care Notes
Water regularly to maintain consistent soil moisture, especially during dry periods. Apply a balanced, slow-release fertilizer in early spring as new growth emerges. Slugs and deer may damage foliage; monitor and manage as needed in typical hosta-growing zones.
