Overview

Registered in 2007, *Hosta* 'Iroquois' is a large cultivar resulting from a cross between *Hosta* 'Blue Steel' (pod parent) and a seedling of *Hosta* 'Dorothy Benedict' (pollen parent). It is visually distinctive for its intensely blue-green, nearly round leaves with heavily puckered and humped surfaces between the veins, combined with a glaucous bloom on both leaf surfaces.

In the Garden

*Hosta* 'Iroquois' forms an upright mound reaching 26 inches (66.0 cm) in height and 42 inches (106.7 cm) in diameter at maturity, with a slow growth rate. It performs best in partial to full shade, as is typical for blue-leaved hostas, where its glaucous bloom remains most pronounced. The substantial leaf size and corrugated texture make it a strong specimen plant or a bold accent in mixed shade borders.

Care Notes

Provide consistent moisture, particularly during dry periods, to maintain leaf turgor and the integrity of the glaucous coating. Apply a balanced, slow-release fertilizer in early spring as new growth emerges. Slugs may damage the broad leaves in damp conditions, though the heavy corrugation offers some physical resistance; deer will browse the foliage. This cultivar is hardy in typical hosta-growing zones.
