Overview
Registered in 1969 by M. Armstrong, this medium-sized cultivar is a hybrid of *Hosta* 'Tokudama'. It is visually distinctive for its blue-green foliage with pronounced blue-gray margins, creating a two-toned effect across its broadly ovate leaves.
In the Garden
Hosta 'Rough Waters' reaches a mature diameter of 24 inches (61.0 cm) and a height of 16 inches (40.6 cm), making it suitable for mid-border positions in partial to full shade. Its blue-green leaves pair well with yellow-foliaged companions such as *Hosta* 'Gold Standard' or with fine-textured ferns. The plant is not suited for containers due to its medium size.
Care Notes
Provide consistent moisture during the growing season, particularly in warmer climates. Apply a balanced fertilizer in early spring as new shoots emerge. Like most hostas, this cultivar is susceptible to slug and deer damage; monitor regularly and apply controls as needed. It performs best in typical hosta-growing zones with adequate winter dormancy.
