Overview

Registered in 1999, 'Brass Horn' is a sport of Hosta 'Fortunei' Stenantha' distinguished by its large, blue-green leaves with wide golden yellow margins. The foliage exhibits a glaucous bloom on both surfaces and slightly rippled margins, creating a pronounced bicolor effect.

In the Garden

This cultivar forms a dense, mound-like clump reaching 22 inches (55.9 cm) in height and 50 inches (127.0 cm) in diameter, with a moderate growth rate. It performs best in partial to full shade, where the blue-green leaf centers and gold margins remain most distinct. The substantial size makes it suitable as a specimen or in mixed shade borders, paired with ferns or other broad-leaved perennials. Its large leaves and upright scapes bearing green flowers in midsummer provide textural contrast.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as growth emerges. As with most hostas, slug and deer damage may occur; monitor regularly and take protective measures if needed.
