Overview
Registered in 1999, 'Rock and Roll' is a large hosta cultivar of unknown parentage, distinguished by its intensely blue-green leaf margins and heavy glaucous bloom on both leaf surfaces. The leaves are cordate at the base, measuring 10.5 inches (26.7 cm) long and 9.5 inches (24.1 cm) wide, with 16 to 18 vein pairs.
In the Garden
This cultivar forms an upright, moderate-growing clump reaching 30 inches (76.2 cm) in height and 54 inches (137.2 cm) in diameter. It performs best in partial to full shade, where the glaucous blue-green foliage retains its color. The substantial size makes it suitable as a specimen or in the middle to back of shaded borders, paired with ferns or other shade-tolerant perennials.
Care Notes
Provide consistent moisture, especially during establishment, and apply a balanced fertilizer in early spring as new growth emerges. Like most large-leaved hostas, 'Rock and Roll' may require protection from slugs and deer in typical hosta-growing zones.
