Overview
Registered in 1999, Hosta 'Key West' is a giant cultivar resulting from a cross between H. nigrescens 'Elatior' (pod parent) and H. 'High Noon' (pollen parent). It is visually distinctive for its large, cordate-based leaves that are green with greenish-yellow, slightly rippled margins, and for its upright, fast-growing habit.
In the Garden
'Key West' reaches a mature size of 29 inches (73.7 cm) in height and 45 inches (114.3 cm) in diameter, making it suitable as a specimen or background plant in partial to full shade. Its substantial leaves and upright form pair well with ferns, astilbes, and other shade-tolerant perennials. Due to its giant size, it is not recommended for container cultivation.
Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like many large-leaved hostas, it may be susceptible to slug damage; monitor and manage as needed. It is hardy in typical hosta-growing zones.
