H. ‘Sea Hero’

Overview

Registered in 2009 by K. Walek of the American Hosta Society, 'Sea Hero' is a large, mound-forming hosta cultivar of unknown parentage. It is distinguished by its intensely blue-green, deeply corrugated, broadly ovate leaves with a glaucous bloom on both surfaces and slightly rippled margins.

In the Garden

'Sea Hero' forms a dense mound 16 inches (40.6 cm) tall and 46 inches (116.8 cm) in diameter, with a slow growth rate. It performs best in partial to full shade, typical for blue-leaved hostas, where the glaucous bloom remains most pronounced. Its large size and bold texture make it suitable as a specimen or accent in shaded borders, paired with ferns, heucheras, or fine-textured groundcovers.

Care Notes

Water regularly during dry periods to maintain soil moisture, and apply a balanced fertilizer in early spring as new growth emerges. The thick, corrugated leaves offer moderate resistance to slugs, though standard slug control measures may still be needed in damp conditions; deer may browse the foliage.
