H. ‘Mellow Yellow’

Overview

Registered in 2010 by R. Kuenster of the American Hosta Society, 'Mellow Yellow' is a large hosta cultivar distinguished by its blue-green leaves with broad, golden yellow margins. The leaf surface is heavily corrugated with deep veining and a dull to glaucous bloom above, while the underside exhibits a slightly shiny to glaucous texture.

In the Garden

This cultivar forms a mound-like clump reaching 18 inches (45.7 cm) in height and 26 inches (66.0 cm) in diameter, with a moderate growth rate. It performs best in partial to dappled shade, where the blue-green center and gold margins remain most stable. The substantial foliage pairs well with ferns, astilbes, and other shade-tolerant perennials. Its large size makes it unsuitable for containers but effective as a specimen or in mass plantings.

Care Notes

Provide consistent moisture, particularly during dry periods, and apply a balanced slow-release fertilizer in early spring as new growth emerges. Like most hostas, this cultivar is susceptible to slug and deer damage, so appropriate management measures may be necessary in areas where these pests are prevalent.
