Overview

Registered in 1990 by P. Banyai, Hosta 'Key Lime' is a medium-sized cultivar derived from a hybrid of H. montana. It is visually distinctive for its cordate, green leaves with light yellow-green margins, producing a two-tone effect that persists through the growing season.

In the Garden

This cultivar reaches a mature spread of 26 inches (66.0 cm) and a height of 13 inches (33.0 cm), making it suitable for mid-border positions in partial to full shade. Its medium size and upright leaf habit pair well with ferns, Heuchera, or other shade-tolerant perennials. It is not typically recommended for container culture due to its spreading habit.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. 'Key Lime' shows typical hosta susceptibility to slugs and deer, so protective measures may be needed in gardens where these pests are prevalent.
