DIFFERENT TYPES OF HEATHERS AND HEATHS IN THE WORLD
From a gardening point of view, when we speak of heather, we refer to three different genera:
– Genus Calluna, to which common heather (Calluna vulgaris) belongs
– Heath species belonging to the genus Erica.
– Heath species belonging to genus Daboecia
Although botanically they are different plants, they are all grouped within the same crop group because, in addition to being similar in shape, they share similar growing conditions except their resistance to cold.
Of course, common heather (Calluna vulgaris) can not withstand the same temperature conditions being a plant which, in the wild, lives in cold northern areas or in very high places than other heaths species living in warmer or even warmer areas.
However, leaving aside this consideration, the conditions of cultivation of all heathers and heaths , in terms of their water needs, light requirements, soil types, leaf permanence, resistance and ease of cultivation, etc. are practically the same .
How many kinds of heather or heaths are there?
Within the genus Calluna there is only one species, the common heather (Calluna vulgaris), although we have many cultivars obtained from this species. In the UK alone it is estimated that there are more than 400.
The genus Erica has more than 800 species of heaths , most of them native to South Africa. There are also some that are European and a smaller number distributed in other parts of Africa.
South African species are noted for their long tubular flowers. They are species that can only live in climates with mild winters. European species are very resistant to cold and are different from African species because they have smaller bell-shaped flowers. They are also more resistant to cold.
The Daboecia genus consists of only two species (Daboecia cantabrica and Daboecia azorica). They are two species of heath native to western Europe and the Azores, respectively. They produce flowers with the floral tube very narrow to the end.
The flowers of the genus Daboecia grow on leafless peduncles and, unlike the rest of heathers, the floral tube falls after flowering
Varieties of common heather (Genus Calluna)
Among the main varieties used in gardening we have some that stand out because they are very low (dwarf varieties) or very high. Others stand out because of the colors of their flowers or the color of their leaves. Among all of them, we highlight the following classes, types or varieties of heather in gardening:

Other species and varieties of heaths (Genus Erica or Daboecia)
– Erica arborea – Giant heath or tree heath: 600 cm. White flowers. Flowers in spring. It is the highest heath, being able to measure from about 20 cm to the more than 6 meters that reach some arboreal forms of Africa, where it forms part of the rainforest. In the Canary Islands it abounds in the Laurisilva. Its trunk is used in the manufacture of pipes.
It is the heath with a widest distribution, forming large groups scattered by different parts of the world (Mediterranean maquia, Portugal and Azores, East of equatorial Africa (The Ruwenzori chain, the mountains of the Cameroon, Plateau of Ethiopia). Zones 8-10
