Overview

A sport of *Hosta* 'First Frost' registered in 2010, 'Permafrost' is a medium-sized cultivar distinguished by its blue-green leaves with unusually wide golden yellow to creamy white margins. The margins measure 0.75 to 1 inch (1.9 to 2.5 cm) across, notably broader than those of its parent, and retain a flat, non-undulate form.

In the Garden

'Permafrost' forms a dense, mound-like clump reaching 14 inches (35.6 cm) in height and 36 inches (91.4 cm) in diameter, with a moderate growth rate. It performs best in partial to full shade, where the blue-green leaf centers and gold margins maintain good contrast. The 24- to 30-inch (61.0 to 76.2 cm) green scapes bear lavender flowers in midsummer. Suitable for shaded borders, woodland gardens, or as a groundcover beneath deciduous trees, it pairs well with ferns, heucheras, and other shade-tolerant perennials.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. As with most hostas, slug and deer damage may occur; monitor regularly and take protective measures if necessary. 'Permafrost' is hardy in typical hosta-growing zones.
