H. ‘Ohh! Blue Otto’

Overview

Registered in 2009 from a seedling of unknown origin, 'Ohh! Blue Otto' is a medium-sized hosta distinguished by its intense blue-green foliage that retains color well into autumn. The ovate, lightly cupped leaves feature a glaucous bloom on the upper surface, slightly rippled margins, and moderate corrugation, giving the plant a textured, substantial appearance.

In the Garden

This cultivar forms a dense, mound-like clump reaching 20 inches (50.8 cm) in diameter and 10 inches (25.4 cm) in height, with a slow growth rate. It performs best in partial to full shade, typical for blue-leaved hostas, where the glaucous bloom is most pronounced. Its compact size and excellent substance make it suitable for border fronts, rock gardens, or container culture, and it 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. As with most hostas, slug and deer damage may occur; monitor and manage as needed.
