About Daboecia cantabrica: St Dabeoc’s heath, Irish bell heather, Irish heath, Cantabrian heath

Daboecia is closely related to the genus Erica (heath) that is popular in winter gardens. Daboecia is native to western Ireland and northern Spain and found along western France. It is also known as St Dabeoc’s heath, Irish bell heather, Irish heath or Cantabrian heath, and often grouped with heathers and heaths. It has an attractive pendent urn or bell-shaped flower which blooms from late spring through to early to mid autumn – sometimes longer during mild fall weather. It is a little on the tender side but can withstand the winters in zones 7 – 9.

Daboecia cantabrica or Irish heath makes a beautiful addition as a summer ground cover or in a mixed border and adding colour in an autumn garden. Flowers range from white, pink and deep purple.

They also look lovely in a planter on your patio. Planting the Irish heath in a garden pot is a good option for colder regions where it can be moved to a more sheltered location, protecting it from freezing winters during it dormancy. Add to your garden to support pollinators (bees, butterflies). Ecological part of biodiverse heathland ecosystems.

Where to Plant and How to Grow Daboecia cantabrica

Daboecia thrives when planted in fertile, moist, well-drained acidic soil in a sunny location, with a little shade during the scorching summer months. Plant deeply so that the lower leaves touch the top of the soil. Do not plant in clay soils or areas prone to heavy frost. Prefers acidic (pH 4.5–6.0), sandy, or peaty soils with good drainage. 

Daboecia is not as drought tolerant as heathers and will need regular watering. Avoid waterlogged conditions.

Though Daboecia is an evergreen, it can be more of a semi-deciduous shrub in colder winter regions. It is best to plant a new daboecia in the autumn time. If planted in a garden pot, move it in winter to a sheltered location against the house and under the roof overhang, where it will be protected from freezing winds and not be saturated during the rainy season.

Propagate via semi-hardwood cuttings or seeds.

Generally pest and disease resilient but susceptible to root rot in poor drainage. Occasional aphid infestations. And for the most part, deer resistant.

How to Prune and Deadhead Daboecia cantabrica

Your daboecia will benefit from a hard prune down to the base early spring once the frost threat is gone. It can tolerate further pruning if control is needed to maintain growth.
