H. ‘Big Mo’

Overview

Registered in 1990 by R. Stephens, 'Big Mo' is a giant blue-green hosta derived from a hybrid of *H. montana*. Its most distinctive features are the exceptionally large, heavily veined leaves—14 inches (35.6 cm) long and 10.5 inches (26.7 cm) wide—with dark blue-green margins and 17 pairs of veins.

In the Garden

'Big Mo' reaches a mature spread of 52 inches (132.1 cm) and a height of 24 inches (61.0 cm), with scapes rising to 34 inches (86.4 cm). It performs best in partial to full shade, where its blue-green coloration remains most intense. Its substantial size makes it suitable as a specimen plant or as a backdrop for smaller shade perennials such as ferns and astilbes.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most large-leaved hostas, 'Big Mo' is susceptible to slug and deer damage in typical hosta-growing zones.
