H. ‘Sunny Isle’

Overview

Registered in 1997 with parentage unknown, 'Sunny Isle' is a small hosta distinguished by its green leaves with yellow to yellowish-green, slightly rippled margins. The leaf surface is dull above and slightly shiny beneath, with seven pairs of veins and a tapered base.

In the Garden

This cultivar forms a compact, mound-like clump reaching approximately 23 inches (58.4 cm) in diameter and 9.5 inches (24.1 cm) in height, with a moderate growth rate. It performs best in partial to full shade, typical for most hostas, and is well-suited to small gardens, rockeries, or front-of-border positions. Its small size makes it an excellent candidate for container cultivation or as an edging plant alongside other small perennials such as heucheras or ferns.

Care Notes

Provide consistent moisture during the growing season, particularly in warmer climates, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, 'Sunny Isle' is susceptible to slug and deer damage, so appropriate deterrents or barriers may be necessary in areas where these pests are prevalent.
