H. ‘Kasseler Blue’

Overview

Registered in 2008 by P. & J. Ruh, 'Kasseler Blue' is a small hosta cultivar of unknown parentage, distinguished by its dark blue-green, ovate leaves with slightly rippled margins and a subtle sheen on both surfaces. The leaves are lightly twisted, folded, and wavy, contributing to an open growth habit that sets it apart from denser blue-green cultivars.

In the Garden

'Kasseler Blue' reaches a mature diameter of 17 inches (43.2 cm) and a height of 11.5 inches (29.2 cm), with an upright form and slow growth rate. It performs best in partial to full shade, typical for blue-leaved hostas, and is well-suited for small garden spaces, rock gardens, or the front of borders. Its compact size also makes it a candidate for container culture. Companion plants that prefer similar conditions, such as ferns, heucheras, or small woodland perennials, complement its open, textured foliage.

Care Notes

Water regularly to maintain consistent soil moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. As with most hostas, slug and deer damage may occur in typical hosta-growing zones, so monitoring and protective measures are advisable.
