| Year registered | 2014 |
|---|---|
| Section class | I-4b (Giant) |
Overview
Registered in 2014 as a sport of Hosta 'Parhelion', 'Icy Halo' is a giant hosta distinguished by its exceptionally large leaves with a medium green center and a 0.5-inch (1.3 cm) wide, creamy white to white margin. The leaf surface is slightly shiny above and dull beneath, with broadly ovate blades that are lightly cupped, folded, and wavy at the edges.
In the Garden
This cultivar forms a mound-like clump reaching 28 inches (71.1 cm) in height and 36 inches (91.4 cm) in diameter, with a fast growth rate. It is best suited to partial to full shade in typical hosta-growing zones, where its substantial foliage provides a strong textural presence. The large leaves pair well with ferns, astilbes, and other shade perennials; due to its giant size, it is not recommended for container cultivation.
Care Notes
Provide consistent moisture during the growing season, applying a balanced fertilizer in early spring as new shoots emerge. Like most hostas, 'Icy Halo' is susceptible to slug and deer damage, and protective measures may be necessary in areas where these pests are prevalent.
