H. ‘Blackjack’

Overview

Registered in 1990 by C. Owens, this giant variegated hosta resulted from a cross between *H.* 'Mira' (pod parent) and *H. sieboldiana* (pollen parent). 'Blackjack' is visually distinctive for its very large, heavily textured leaves with dark green margins and a broad, irregular yellow to cream center that matures to white.

In the Garden

'Blackjack' forms a substantial clump reaching 24 inches (61.0 cm) in height and 58 inches (147.3 cm) in diameter, making it suitable as a specimen or background plant in shaded borders. It performs best in partial to full shade, where the variegation remains stable, and pairs well with ferns, *Heuchera*, and other shade-tolerant perennials. Its giant size precludes container cultivation for most gardeners.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most large-leaved hostas, 'Blackjack' is susceptible to slug and deer damage; regular monitoring and appropriate controls are recommended.
