Overview
Registered in 1982 by P. Aden, this large hosta is a hybrid of *H. 'Flamboyant'* (pod parent) and *H. 'Fascination'* (pollen parent). *Hosta* 'Double Edge' is visually distinguished by its apple-green leaves with yellow and white margins, a tri-colored effect that sets it apart from standard variegated cultivars.
In the Garden
'Double Edge' forms a substantial clump reaching 18 inches (45.7 cm) in height and 26 inches (66.0 cm) in diameter, with individual leaves measuring 10 inches (25.4 cm) long and 8 inches (20.3 cm) wide. It performs best in partial to full shade, typical for hostas, and pairs well with ferns, astilbes, and other shade-tolerant perennials. The scape height is recorded as 24 inches (61.0 cm), though some sources note variability.
Care Notes
Provide consistent moisture during the growing season, particularly in warmer climates. Apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, 'Double Edge' is susceptible to slug and deer damage; monitor accordingly in typical hosta-growing zones.
