Beach Wormwood

Artemisia stelleriana

The Story

Plant Bio

Artemisia stelleriana, beach wormwood, is a low creeping perennial of northern coasts, about eight inches high and spreading two feet. Deeply lobed silvery-white leaves are densely felted with hair on both surfaces, giving an almost artificial brightness, and small yellow cup-shaped flowers appear in summer above the mat.

It is a true dune plant, holding loose sand with creeping stems and shrugging off salt spray, which makes it one of the few silver-foliage plants that survives an exposed coastal garden. The felted hairs that give the colour also reduce water loss, so it needs sharp drainage and resents rich, damp soil more than it resents drought.

Uses & Benefits:

Ornamental UsesBrilliant silver-white deeply lobed foliage that holds colour all season.
Practical UsesBinds loose sand and tolerates salt spray, wind and drought on exposed coasts.
Ecological BenefitsA native dune stabiliser on northern coasts, with flowers that draw bees and butterflies.

Planting

How to Grow

  1. Plant in full sun in sandy, sharply drained soil.
  2. Use it on dunes, banks and coastal borders.
  3. Water only while establishing.
  4. Do not feed; lean soil keeps the silver bright.
  5. Shear after flowering to keep growth compact.
  6. Divide creeping stems to spread it.

Pro Tip

The silver comes from felted hairs that also conserve water — rich damp soil dulls the colour and rots the plant.

Yes — Beach Wormwood is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Beach Wormwood bloom?

Beach Wormwood typically blooms in mid-summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Beach Wormwood need full sun?

Beach Wormwood does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Beach Wormwood drought tolerant?

Yes — once established (usually after the first full season), Beach Wormwood handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
