H. ‘Bluer than Blue’

Overview

Registered in 2013, *Hosta* 'Bluer than Blue' is a large, slow-growing cultivar of unknown pollen parentage. Its primary distinction is an intense, powder-blue leaf coloration that persists longer into the growing season than that of its pod parent, with deeply corrugated, nearly round leaves that form an upright to mound-like habit.

In the Garden

'Bluer than Blue' reaches a mature spread of 36 inches (91.4 cm) and a height of 18 inches (45.7 cm), with scapes rising 30 to 35 inches (76.2 to 88.2 cm). It performs best in partial to full shade, typical for blue-leaved hostas, where its color intensity is maximized. The large, textured foliage pairs well with ferns, heucheras, and other shade perennials; its slow growth rate makes it suitable for specimen placement or as a focal point in shaded borders.

Care Notes

Provide consistent moisture during establishment and throughout dry periods; apply a balanced, slow-release fertilizer in early spring as new growth emerges. The thick, corrugated leaves offer moderate slug resistance, though standard slug controls may still be warranted in damp conditions.
