Overview

Registered in 2005, Hosta 'Blue Lightning' is a sport of Hosta 'Blue Umbrellas' distinguished by its blue-green leaves with white margins and a fast growth rate. The foliage is heavily streaked with blue, green, yellow, and cream tones, and both leaf surfaces bear a glaucous bloom.

In the Garden

This medium-sized cultivar forms a mound 14 inches (35.6 cm) tall and 24 inches (61.0 cm) in diameter, with leaves 9 inches (22.9 cm) long and 4.5 inches (11.4 cm) wide. It performs best in partial to full shade, typical for blue-leaved hostas, and its rapid spread makes it suitable for filling gaps in shaded borders or woodland gardens. Companion plants include ferns, Heuchera, and Astilbe.

Care Notes

Water regularly during dry periods to maintain consistent soil moisture, and apply a balanced slow-release fertilizer in early spring. The glaucous foliage may be susceptible to slug damage in humid conditions, and deer browsing is possible in typical hosta-growing zones.
