Cape Verde, as some individuals were observed to have similarities with the Cape Verdean subspecies (subsp. caboverdeana); there are around 200-300 individuals on remote sites in the island of São Jorge and a few more on other islands and is unknown if these populations can be considered native or the result of an early introduction. Uses When the bark or leaves are cut they secrete a reddish resin, one of several sources of substances known as dragon's blood. Red resins from this tree contain many mono- and dimeric flavans that contribute to the red color of the resins. Dragon's blood has a number of traditional medical uses, although dragon's blood obtained from Dracaena draco was not known until the 15th century, and analyses suggest that most dragon's blood used in art was obtained from species of the genus Daemonorops. The primary and secondary plant body are the site of the secretory plant tissues that form dragon's blood. These tissues include ground parenchyma cells and cortex cells. Dragon's blood from Dracaena draco and Dracaena cinnabari can be distinguished by differences in 10 compounds and a dominant flavonoid DrC11 missing in Dracaena draco. The Guanches worshiped a specimen in Tenerife, and hollowed its trunk into a small sanctuary. Humboldt saw it at the time of his visit. It was tall and in circumference, and was estimated to be 6000 years old. It was destroyed by a storm in 1868. Cultivation Dracaena draco is cultivated and widely available as an ornamental tree for parks, gardens, and drought tolerant water conserving sustainable landscape projects. It has gained the Royal Horticultural Society's Award of Garden Merit. In 2017, the city of Angra do Heroísmo (Terceira Island) planted a grove of 200 dragon trees. The Museum of Wine on Pico Island, Azores, has one of the largest concentrations of this species in Macaronesia, some being more than 100 years old. Symbolism Dracaena draco is the natural symbol of the island of Tenerife, together with the blue chaffinch.
