H. ‘Ocean Isle’

Overview

Registered in 2006, *Hosta* 'Ocean Isle' is a sport of *H.* 'El Dorado' distinguished by its giant size and bold, heavily rippled golden yellow margins surrounding a medium blue-green leaf center. The cultivar's broad, ovate leaves with cordate bases display a glaucous bloom on both surfaces and are notable for their high vein count (16 to 20 pairs), moderate corrugation, and wide margins measuring 1.5 to 3 inches (3.8 to 7.6 cm) across.

In the Garden

This hosta forms a dense, mound-like clump reaching 20 inches (50.8 cm) in height and 45 inches (114.3 cm) in diameter, with a moderate growth rate. It performs best in partial to full shade, where the blue-green centers contrast effectively with the gold margins; excessive sun may scorch the thin, rippled edges. The large scale makes it suitable as a specimen or focal point in shaded borders, and its substantial leaves pair well with ferns, astilbes, or other shade-tolerant perennials of contrasting texture.

Care Notes

Water regularly to maintain consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as growth emerges. Like most large-leaved hostas, 'Ocean Isle' is susceptible to slug and deer damage, so protective measures may be necessary in areas where these pests are prevalent.
