Smoke and Mirrors Coral Bells: Pewter Gray at the Bed's Shady Edge
Save
Smoke and Mirrors coral bells offers something unusual in a world full of green: cool, smoky gray. New leaves open pewter gray with a rosy blush, then mature to solid soft gray with darker veins. In midsummer, very tall dark stems carry narrow spikes of light rose bells well above the low mound.
Its gray tones are a natural echo of lavender's foliage, but its water needs are different, so placement matters.

Using gray to link sun and shade
Many gardens have a lavender bed that fades into a shadier area along a fence, a building or a tree line. That transition is where Smoke and Mirrors shines. Its gray leaves carry lavender's color into the cooler zone, so the planting feels continuous. Just keep it out of lavender's driest, leanest ground: it wants regular water, which lavender does not, so give it its own spot a few feet away where you can water without soaking lavender crowns.
It is documented as vigorous and resistant to melting out in high heat and humidity, which is reassuring through a sticky Michigan July. In the shade bed it also contrasts well with chartreuse hostas and dark ferns. Try placements in the Companion Plant Planner.
Care notes
- Soil: average to fertile and well drained. Crown rot in wet, poorly drained soil is the main problem.
- Water: regularly, at the base, and not late in the day to limit leaf diseases.
- After bloom: cut spent flower stems to the base.
- Winter: evergreen to semi-evergreen in Michigan, and the winter chill helps it flower. Mulch after the ground freezes to limit frost heaving.
- Spring: press heaved crowns back in, and trim tattered leaves and old stems.
Edging and containers
A row of gray mounds makes a calm, elegant edging along a path, and in a container the smoky foliage pairs beautifully with silver and purple plants. The rose flower stems are fair for small arrangements.
Two tray sizes
Smoke and Mirrors is offered as a 72-cell plug tray and a 20-cell plug tray. Pick the 72-cell tray for long edgings and larger plantings, or the 20-cell tray for fewer, larger plugs. See each product page for current availability.
Frequently asked questions
Can it grow in the lavender bed itself?
It is better beside it. It needs more regular water than lavender, so plant it at a shadier, moister edge.
Why did it not flower this year?
It needs a cold winter to bloom well. A mild winter or a very young plant can mean fewer flower stems.
Does the leaf color change?
Yes. New leaves are pewter with a rosy blush, maturing to soft gray with darker veins.
