H. ‘Ohh! Blue Bruiser’

Overview

Registered in 2011 by an unnamed originator, *Hosta* 'Ohh! Blue Bruiser' is a giant-sized cultivar notable for its rapid growth rate and distinctive blue-green foliage that maintains a glaucous bloom on both leaf surfaces. The plant produces broadly ovate, cordate-based leaves up to 15 inches long and 12 inches wide, with 16 to 17 pairs of veins, a lightly cupped form, moderately wavy margins, and light corrugation.

In the Garden

This cultivar reaches a mature spread of 45 inches (114.3 cm) and a height of 32 inches (81.3 cm), with upright scapes rising 38 to 46 inches (96.5 to 116.8 cm) above the foliage. It performs best in partial to full shade, as is typical for blue-leaved hostas, where the glaucous bloom is best preserved. Its substantial size makes it suitable as a specimen or background plant in shaded borders, and it pairs well with ferns, astilbes, and other shade-tolerant perennials.

Care Notes

Provide consistent moisture, particularly during establishment, and apply a balanced fertilizer in early spring as new growth emerges. The thick, corrugated leaves offer moderate resistance to slugs, though standard preventative measures are advisable in damp conditions; deer may browse the foliage.
