Silver Bullet Hosta: A Thick Blue Dome That Shrugs Off Slugs
Save
Silver Bullet hosta looks like a mouse-ears hosta that kept growing. Its very thick, nearly round, powdery blue leaves pack tightly into a rounded dome about 11 inches tall, with a cool silvery cast and a slight cupping. Technically it is a medium hosta, spreading 20 to 26 inches, but it has the neat look of a small one.
Like every hosta, it is a shade plant, so it belongs in a different part of the garden from your lavender.

The slug question
Thin-leaved hostas can look like lace by August in a wet Michigan summer. Silver Bullet's thick, waxy leaves resist slug damage better than most hostas, which makes it a good choice for gardeners who are tired of the nightly patrol. It is not slug-proof, so tidy up debris in fall and give the clump some airflow during long wet spells.
Where it goes in a lavender garden
Silver gray lavender in the sun and powdery blue hosta in the shade make a nice pair of cool tones across a property, even though the two never share soil. Use Silver Bullet as a low edging along a shaded path, a front-row plant in a woodland bed, or the centerpiece of a shaded pot by the door. Its tight dome contrasts well with lacy ferns and the upright plumes of astilbe. Map the sunny and shady beds in the Companion Plant Planner.
Care notes
- Light: the blue comes from a waxy coating that melts away in heat and strong sun. Afternoon shade keeps it blue longest.
- Soil and water: rich, humus-heavy and evenly moist, but well drained. Water deeply in dry spells, especially the first summer.
- After bloom: cut spent scapes.
- Health: discard plants with mottled, streaked leaves, a sign of hosta virus. Watch for crown rot in hot, wet weather.
- Fall: cut leaves down after a hard frost to remove slug eggs and debris.
- Spring: divide crowded clumps as shoots emerge.
Tray options
Silver Bullet comes as a 72-cell plug tray for growers and big shade plantings, and as a 20-cell plug tray with fewer, larger plugs. See each product page for current availability.
Frequently asked questions
Is Silver Bullet a miniature hosta?
Not quite. It is classed as a medium hosta but stays low and compact, so it fills the same roles as a small one.
Can it take sun?
A little gentle morning sun is fine. Hot afternoon sun strips the blue coating and can scorch the leaves.
Is it safe around pets?
Hosta foliage is listed as toxic to dogs and cats. Keep it away from pets that like to chew plants.
