Hosta ‘Rosedale Gee-whiz’ is a registered cultivar () .

Year registered2000
Section classIV-7 (Small)

Overview

Registered in 2000 by Rosedale Gardens, this small hosta cultivar is a hybrid of Hosta 'RD-BS' (pod parent) and Hosta '900' (pollen parent). Its primary distinction lies in the variegated leaves with streaked margins, a pattern that sets it apart from more uniformly edged cultivars.

In the Garden

With mature leaves reaching 6 inches (15.2 cm) in length and 2.5 inches (6.4 cm) in width, 'Rosedale Gee-whiz' forms a compact clump suitable for the front of a shaded border or rock garden. It performs best in partial to full shade, where its variegation remains most stable, and pairs well with other small hostas, ferns, or woodland perennials such as Heuchera and Tiarella. Its small size also makes it an appropriate choice for container plantings.

Care Notes

Water regularly to maintain consistent soil moisture, particularly during dry spells, and apply a balanced slow-release fertilizer in early spring as new growth emerges. Like most hostas, it is susceptible to slug and deer damage, so protective measures may be necessary in areas where these pests are prevalent.
