H. ‘Katherine S. Mahoney’

Overview

Registered in 2006, 'Katherine S. Mahoney' is a medium-sized hosta of unknown parentage, notable for its variegated foliage and late-blooming habit. The leaves are ovate with rounded bases, medium green with slightly rippled margins, and exhibit a slightly shiny upper surface with a very shiny underside, creating a distinctive two-tone luster.

In the Garden

This cultivar forms a dense, mound-like clump reaching 18 inches (45.7 cm) in height and 41 inches (104.1 cm) in diameter, with a fast growth rate. It performs best in partial to full shade, as typical for hostas, and its medium size makes it suitable for mid-border positions or as a groundcover in shaded beds. The pale lavender flowers, arranged on short scapes 15 to 18 inches (38.1 to 45.7 cm) tall, appear late in the season, extending the garden's interest into autumn.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, 'Katherine S. Mahoney' is susceptible to slug and deer damage; regular monitoring and appropriate barriers may be necessary in areas where these pests are prevalent.
