Section classIII-6a (Medium)

Overview

A sport of *Hosta* 'Captain Kirk', registered in 2007, 'Vulcan' is a medium-sized cultivar distinguished by its blue-green leaf centers and white margins. The leaf center and margin overlap to produce a chartreuse yellow zone, a notable feature that contributes to its visual interest.

In the Garden

'Vulcan' forms a mound-shaped clump reaching 28 inches (71.1 cm) in diameter and 17 inches (43.2 cm) in height, with a moderate growth rate. It performs best in partial to full shade, typical for hostas, and is suitable for borders, woodland gardens, or as a specimen plant. Its medium size allows pairing with smaller perennials such as ferns or heucheras, though it is not recommended for containers due to its mature spread.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, 'Vulcan' is susceptible to slug and deer damage; monitor regularly and use barriers or repellents as needed.
