As bold as the force of nature it was named after, ‘Thunderbolt’ provides an explosion of energy to the garden with heavily corrugated, heavily substanced, blue-green leaves that grow aggres_sively to form a beefy, spreading mound of foliage that jumps into your consciousness with a flash of strong yellow variegation at the leaf center that fades to white as the season progresses. It’s an outstanding looking plant that’s made even better by the fact that its foliage is resistant to one of the scourges of the Hosta world ? slugs. ‘Thunderbolt’ will thrive in shady, moist areas and can be used well as a single specimen or grouped to form an electrifying display of foliage in the landscape.
