H. ‘Black and Blue’

Overview

Registered in 2010 by R. Kuenster of the American Hosta Society, 'Black and Blue' is a small hosta cultivar of unknown parentage. It is distinguished by its lance-shaped, blue-green leaves with dark green to light blue, slightly rippled margins, a slightly shiny upper surface, and a glaucous bloom on the underside.

In the Garden

'Black and Blue' forms a compact, mound-like clump reaching 10 inches (25.4 cm) in height and 16 inches (40.6 cm) in diameter, with a moderate growth rate. It performs best in partial to full shade, typical for blue-leaved hostas, and is well-suited for small gardens, rock gardens, or the front of shaded borders. Its small size makes it an excellent candidate for container cultivation, where its leaf color and texture can be appreciated up close. Companion plants might include ferns, heucheras, or other small shade perennials that contrast with its blue-green foliage.

Care Notes

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