Heather

Calluna vulgaris

The Story

Plant Bio

Calluna vulgaris, heather or ling, is a low broadleaf evergreen shrub from Eurasia, four inches to two feet high and spreading one to two feet. Tiny needle-like leaves are held in four opposite ranks along wiry stems, and dense spikes of small urn-shaped flowers in pink, purple or white open from late summer into autumn.

It demands genuinely acid, sharply drained, poor soil — heather fails in ordinary garden ground more often than for any other reason, and no amount of feeding helps. Trim it lightly every spring: unpruned plants go woody and bare at the base within a few years and cannot be cut back into old wood to recover.

Uses & Benefits:

Ornamental UsesDense late-summer flower spikes over evergreen foliage that often bronzes in winter.
Practical UsesThrives on poor acid ground where little else will, and needs no feeding at all.
Ecological BenefitsHigh-value nectar for bees, and the source of the distinctive heather honey.

Planting

How to Grow

  1. Plant only in acid, sharply drained, poor soil.
  2. Give it full sun for the best flower and foliage colour.
  3. Do not feed or add lime or mushroom compost.
  4. Water with rainwater where tap water is hard.
  5. Trim lightly each spring, above the old wood.
  6. Replace plants that have gone woody at the base.

Pro Tip

Trim it every spring without fail — heather does not resprout from bare wood, so one missed year cannot be corrected later.

Common Questions

Heather questions

What zones can Heather grow in?

Heather is hardy in USDA Zones 4–7. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Heather deer resistant?

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

When does Heather bloom?

Heather typically blooms in late summer to fall through early fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Heather need full sun?

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