H. ‘Fort Knox’

Overview

Registered in 1989 by J. & J. Wilkins, this medium-sized hosta cultivar is distinguished by its green leaves with bright yellow margins. The leaf blade measures 8 inches (20.3 cm) in length and 5 inches (12.7 cm) in width, with nine pairs of veins. The plant forms a mound 24 inches (61.0 cm) in height and 44 inches (111.8 cm) in diameter, derived from a cross between *H.* 'Gold Regal' (pod parent) and *H.* 'Aspen Gold' (pollen parent).

In the Garden

'Hosta 'Fort Knox' performs best in partial to full shade, as is typical for variegated hostas, where the gold margins remain most vibrant. At maturity, it forms a substantial clump nearly 4 feet (1.1 m) across, making it suitable as a mid-border specimen or groundcover beneath deciduous trees. It pairs well with ferns, astilbes, and other shade-tolerant perennials; its size precludes container cultivation for most gardeners.

Care Notes

Provide consistent moisture, particularly during dry spells, and apply a balanced slow-release fertilizer in early spring as new growth emerges. Like most hostas, it is susceptible to slug and deer damage, so protective measures may be necessary in areas where these pests are prevalent.
