Year registered2012
Section classI-1 (Giant)

Overview

Registered in 2012, this giant hosta cultivar produces exceptionally large, broadly ovate leaves with medium green centers and very slightly rippled margins, complemented by distinct vein patterns. The plant forms a substantial mound reaching 23 inches (58.4 cm) in height and 57 inches (144.8 cm) in diameter, with a moderate growth rate.

In the Garden

'Hosta 'Ruth Reed Mraz' performs best in partial to full shade, where its massive foliage can develop fully without scorching. Given its giant mature dimensions—nearly 5 feet across—it requires ample spacing and serves effectively as a specimen plant or as a bold accent in shaded borders and woodland gardens. Its substantial leaves pair well with finer-textured shade perennials such as ferns, astilbes, or Japanese forest grass.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Standard slug and deer deterrents are advisable, as the large leaves are attractive to both pests.
