| Year registered | 2010 |
|---|---|
| Section class | III-2 (Medium) |
Overview
Registered in 2010, 'Rock of Gibraltar' is a sport of *Hosta* 'Chain Lightning' that distinguishes itself through its blue-green foliage, a departure from the lighter green of its parent. This medium-sized cultivar forms a dense, mound-like clump with broadly ovate, deeply corrugated leaves that display a distinct glaucous bloom on both surfaces.
In the Garden
'Rock of Gibraltar' reaches 18 inches (45.7 cm) in height and spreads to 30 inches (76.2 cm) in diameter, with a fast growth rate that allows it to fill space efficiently. Its blue-green, moderately cupped leaves with flat margins and wavy edges make it suitable for partially shaded borders or woodland gardens, where its corrugated texture provides visual contrast against finer-textured perennials such as ferns or *Heuchera*.
Care Notes
Provide consistent moisture during dry periods, particularly in the first growing season, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, 'Rock of Gibraltar' is susceptible to slug and deer damage in typical hosta-growing zones.
