H. ‘Great Plains’

Overview

Originating from the work of O. Petryszyn and W. Brincka and registered in 1994, 'Great Plains' is a giant hosta distinguished by its substantial blue-green foliage and semi-upright growth habit. The leaves are large, measuring 16 inches (40.6 cm) long and 12 inches (30.5 cm) wide, with a cordate base, smooth gray-blue margins, a slightly shiny upper surface, and a pale dusty blue underside, supported by 12 to 14 vein pairs.

In the Garden

This cultivar reaches a mature spread of 41 inches (104.1 cm) in diameter and a height of 25 inches (63.5 cm), with scapes rising 39 to 42 inches (99.1 to 106.7 cm) above the foliage. It performs best in partial to full shade, typical for blue-leaved hostas, and its large size makes it suitable as a specimen or background plant in woodland gardens and mixed borders. Companion plants such as ferns, astilbes, or shade-tolerant grasses complement its broad, blue-green leaves.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Slugs and deer may damage foliage; monitor regularly and employ control measures as needed in typical hosta-growing zones.
