The Story
Plant Bio
Epacris impressa, the common heath, is an erect, wiry Australian shrub featuring slender, upright branchlets clad in small, rigid, needle-sharp leaves. During its extended flowering season from autumn to spring, the branches are densely packed with tubular, five-indented flowers ranging from white to deep crimson.
As the floral emblem of Victoria, this species is highly prized for its ability to attract native honeyeaters and spinebills with its nectar-rich blooms. The sessile, linear-lanceolate foliage tapers to a sharp, acuminate point that requires careful handling.

Planting
How to Grow
- Select a position in full sun to dappled shade with highly permeable, sandy or gravelly acidic soil.
- Dig a hole twice the width of the root ball and plant gently to avoid disturbing the extremely fine, delicate roots.
- Water in thoroughly and apply a light organic mulch, keeping it clear of the main stem base.
- Maintain regular soil moisture during dry summer periods, ensuring the soil never dries out completely.
Pro Tip
Never prune hard into old, leafless wood, as the plant lacks dormant buds on bare stems and will fail to regenerate.

Care Guide
Do
- Tip-prune lightly immediately after flowering to maintain a bushy habit.
- Water regularly during hot, dry summer months to protect the fine root system.
- Use low-phosphorus native fertilisers very sparingly if at all.
- Ensure excellent soil drainage by planting on sloped ground or in raised beds.
Don't
- Do not prune back into old, bare, brown wood.
- Do not allow the soil to dry out completely during summer.
- Do not use standard high-phosphorus fertilisers.
- Do not let the plant sit in heavy, waterlogged clay or stagnant water.
