Overview
Registered in 2006 by R. Benedict and B. Kuk, *Hosta* 'Roseann Walter' is a large, upright cultivar derived from *Hosta* 'Dorothy Benedict' with an unknown pollen parent. It is distinguished by its medium blue-green, ovate, lightly corrugated leaves with chartreuse gold margins that hold their color until late August.
In the Garden
This cultivar reaches 27 inches (68.6 cm) in height and 23 inches (58.4 cm) in diameter, with a moderate growth rate and upright habit. It performs best in partial to full shade, as typical for blue-green hostas, and its large size makes it suitable for mid-border or specimen placement. The chartreuse gold margins provide contrast against darker green companions such as ferns or heucheras.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most large-leaved hostas, it may be susceptible to slug damage and deer browsing in typical hosta-growing zones.
