Overview

Registered in 2005 by P. & J. Ruh, Hosta 'Black Forest' is a medium-sized variegated cultivar of unknown parentage. It is distinguished by its heavily rippled, medium to light green leaf margins and an unusually dense, folded leaf surface that gives the foliage a distinctly textured appearance.

In the Garden

This cultivar forms a mound-shaped clump reaching 19 inches (48.3 cm) in height and 27 inches (68.6 cm) in diameter, with a moderate growth rate. It performs best in partial to full shade, typical of hosta-growing zones, and its medium size makes it suitable for border fronts, woodland gardens, or shaded containers. The dense, corrugated foliage pairs well with ferns, heucheras, or other shade-tolerant perennials.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, it is susceptible to slug and deer damage, so protective measures may be necessary in areas where these pests are prevalent.
