| Year registered | 2008 |
|---|---|
| Section class | III-5b (Medium) |
Overview
A sport of *Hosta* 'Golden Delight' registered in 2008, 'Roberta' is a medium-sized hosta distinguished by its stable blue-green leaves with broad golden yellow margins. The foliage displays a dull glaucous bloom on both surfaces, with slightly rippled, moderately corrugated margins that contribute to its textural interest.
In the Garden
'Roberta' forms a mound-like clump reaching 18 inches (45.7 cm) in height and 25 inches (63.5 cm) in diameter, with a moderate growth rate. It performs best in partial to full shade, as is typical for blue-green hostas, where the leaf coloration remains most consistent. The 7-inch (17.8 cm) long, broadly ovate leaves with cordate bases pair well with ferns, heucheras, and other shade perennials; its medium size makes it suitable for border fronts or woodland garden mid-layers.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, 'Roberta' is susceptible to slug and deer damage in typical hosta-growing zones.
