Vulcan Hosta: A Bright White Center That Holds Up All Summer
Save
Vulcan hosta is a vigorous, white-centered hosta with broad, heart-shaped leaves. Dark green margins frame each leaf, and streaks of lighter yellow-green jet inward toward the bright white center. Unlike many white-centered hostas, the center holds up well rather than browning out by midsummer.
It grows at a good clip into a rounded mound about 22 inches tall and 3 feet wide. Where your lavender wants the sunniest ground you have, Vulcan is for the darkest.

Light for the dark corners
Every lavender grower ends up with spots where lavender simply will not go: under the big maple, along the north foundation, beside the shed. A white-centered hosta is one of the best ways to make those places glow. Vulcan's centers read almost like light coming through the leaves, especially at dusk.
In a whole-garden plan, let lavender carry the sunny beds with purple and silver, and let Vulcan carry the shade with white and dark green. In late July its light lavender flowers on white scapes give a quiet nod to the lavender blooming in the sun. Use the Companion Plant Planner to place each in its zone.
Good neighbors in the shade
- Ferns: fine fronds contrast with Vulcan's broad leaves.
- Astilbe: feathery plumes add summer color.
- Dark-leaved coral bells: a deep purple leaf next to a white center is striking.
Care notes
- Soil: rich, humus-heavy, evenly moist but well drained.
- Light: the white center tolerates summer better than most, but afternoon shade is still best in hot weather.
- Water: deeply in dry spells, especially the first summer.
- Slugs: they chew holes in wet weather; clean up debris and give clumps airflow.
- Fall: cut the foliage down after a hard frost.
- Spring: divide crowded clumps as shoots appear.
Watch for mottled, streaked leaves, a sign of Hosta Virus X, and discard any affected plant. Crowns can rot in hot, wet weather if the soil does not drain.
Plug tray or bare root
Vulcan is offered as a full 72-cell plug tray for growers and mass plantings, and as a bare root plant for setting a specimen straight into the garden. See each product page for current availability.
