| Year registered | 2004 |
|---|---|
| Section class | I-2 (Giant) |
Overview
Registered in 2004 from unknown parentage, Hosta 'Sunfish Blue' is a giant cultivar distinguished by its intensely blue-green foliage, which carries a glaucous bloom on both the upper and lower leaf surfaces. The leaves are broadly ovate with spear-like tips and cordate bases, measuring up to 17 inches long and 14 inches wide, with flat margins, moderate cupping, and light corrugation.
In the Garden
With a mature diameter of 48 inches and height of 35 inches, 'Sunfish Blue' forms a substantial upright clump suited to partial to full shade, as is typical for blue-leaved hostas. Its large, blue-green leaves provide strong textural contrast when paired with finer-textured shade perennials such as ferns, Heuchera, or Carex. The plant produces green scapes 48 to 50 inches tall, though the flowers are not its primary ornamental feature.
Care Notes
Provide consistent moisture during the growing season, applying a balanced slow-release fertilizer in early spring as new shoots emerge. As with most large-leaved hostas, slug and deer damage can occur and may require management in garden settings.
