Overview

Registered in 1999, *Hosta* 'Rosedale Knox' is a giant-sized cultivar derived from the hybrid *H.* 'RD-BS-1'. It is visually distinctive for its large, green leaves with broad, yellow margins, reaching 15 inches (38.1 cm) in length and 8 inches (20.3 cm) in width.

In the Garden

This cultivar's substantial size makes it suitable as a specimen plant or for the back of a mixed border in partial to full shade. Mature clumps can reach a spread of 4 to 5 feet, requiring ample space. It pairs well with ferns, astilbes, and other shade-tolerant perennials that contrast with its bold 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, slug and deer damage may occur and should be managed through routine garden practices.
