Daboecia /dæˈbʃiə/,[1] St. Dabeoc's heath, is a small genus of flowering plants in the family Ericaceae, containing two evergreen shrubs, closely related to the genus Erica. They are native to cliffs and heathland in south-western Europe.

Description[edit]

They produce urn-shaped flowers in shades of white, pink and red. Daboecia differ from European Erica species in having a substantially larger corolla. The leaves are always alternate in Daboecia, never whorled. The generic name comes from the Irish Saint Dabheog.

Distribution[edit]

Daboecia has an oceanic southern distribution in western Europe, including western Ireland, western France, northwestern Spain, Portugal and the Azores.[2] Like Erica species, and Calluna Daboecia are calcifuges, but will tolerate neutral soils and avoid peat.

Species[edit]

Some botanists regard D. azorica as a subspecies of D. cantabrica, which would render the genus monospecific.

Cultivation[edit]

The two species have been extensively cultivated and hybridised to produce a number of popular garden plants. Cultivars include selections from the hybrid between the two species, which is named Daboecia × scotica.

The following cultivars have gained the Royal Horticultural Society’s Award of Garden Merit (confirmed 2017):[4]

  • D. cantabrica ‘Waley’s Red’[5]
  • D. cantabrica subsp. scotica ‘Silverwells’[6]
  • D. cantabrica subsp. scotica ‘William Hicks’[7]
