|The ancient specimen at Icod de los Vinos, Tenerife|
Dracaena draco, the Canary Islands dragon tree or drago,is a subtropical tree in the genus Dracaena , native to the Canary Islands, Cape Verde, Madeira, and locally in western Morocco, and introduced to the Azores. It is the natural symbol of the island of Tenerife, together with the blue chaffinch.
Dracaena draco is a monocot with a branching growth pattern currently placed in the asparagus family (Asparagaceae, subfamily Nolinoidae). 1.2 metres (4 ft) in height but can grow much faster.When young it has a single stem. At about 10–15 years of age the stem stops growing and produces a first flower spike with white, lily-like perfumed flowers, followed by coral berries. Soon a crown of terminal buds appears and the plant starts branching. Each branch grows for about 10–15 years and re-branches, so a mature plant has an umbrella-like habit. It grows slowly, requiring about ten years to reach
Being a monocotyledon, it does not display any annual or growth rings so the age of the tree can only be estimated by the number of branching points before reaching the canopy. The specimen called "El Drago Milenario" (the thousand-year-old dragon) growing at Icod de los Vinos in northwest Tenerife is the oldest living plant of this species. Its age was estimated in 1975 to be around 250 years, with a maximum of 365 years, not several thousand as had previously been claimed.It is also the largest D. draco tree alive. Its massive trunk comes from the contribution of clusters of aerial roots that emerge from the bases of lowest branches and grow down to the soil. Descending along the trunk, they cling tightly to the trunk, integrate with it and contribute to its radial growth. There is considerable genetic variation within the Canary Island dragon trees. The form found on Gran Canaria is now treated as a separate species, Dracaena tamaranae , based on differences in flower structure. The form endemic to La Palma initially branches very low with numerous, nearly vertical branches arranged fastigately. There is a forest of such trees at Las Tricias, Garafia district, La Palma.
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 70 feet (21 m) tall and 45 feet (14 m) in circumference, and was estimated to be 6000 years old. It was destroyed by a storm in 1868.
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.
Flavan-3-ols are derivatives of flavans that possess a 2-phenyl-3,4-dihydro-2H-chromen-3-ol skeleton. These compounds include catechin, epicatechin gallate, epigallocatechin, epigallocatechin gallate, proanthocyanidins, theaflavins, thearubigins.
Pinus canariensis, the Canary Island pine, is a species of gymnosperm in the conifer family Pinaceae. It is a large, evergreen tree native and endemic to the outer Canary Islands in the Atlantic Ocean. It is a subtropical pine and does not tolerate low temperatures or hard frost, surviving temperatures down to about −6 to −10 °C. Within its natural area, it grows under extremely variable rainfall regimes, from less than 300 mm (12 in) to several thousands, mostly due to differences in mist-capturing by the foliage. Under warm conditions, this is one of the most drought-tolerant pines, living even with less than 200 mm (7.9 in) of rainfall per year. It is the vegetable symbol of the island of La Palma.
Dracaena ( is a genus of about 120 species of trees and succulent shrubs. In the APG IV classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae. It has also formerly been separated into the family Dracaenaceae or placed in the Agavaceae.
Dragon's blood is a bright red resin which is obtained from different species of a number of distinct plant genera: Croton, Dracaena, Daemonorops, Calamus rotang and Pterocarpus. The red resin has been in continuous use since ancient times as varnish, medicine, incense, and dye.
Xanthorrhoea is a genus of about 30 species of flowering plants endemic to Australia. Species are known by the name grass tree.
Daemonorops is a genus of rattan palms in the family Arecaceae found primarily in the tropics and subtropics of southeastern Asia with a few species extending into southern China and the Himalayas.
Samanea saman, also sometimes known as the rain tree, is a species of flowering tree in the pea family, Fabaceae, now in the Mimosoid clade and is native to the Central and South America. Its range extends from Mexico south to Peru and Brazil, but it has been widely introduced to South and Southeast Asia, as well as the Pacific Islands, including Hawaii. Common names include saman, rain tree and monkeypod. It is often placed in the genus Samanea, which by yet other authors is subsumed in Albizia entirely.
Sansevieria is a historically recognized genus of flowering plants, native to Africa, Madagascar and southern Asia, now included in the genus Dracaena on the basis of molecular phylogenetic studies. Common names for the 70 or so species formerly placed in the genus include mother-in-law's tongue, devil's tongue, jinn's tongue, bow string hemp, snake plant and snake tongue. In the APG III classification system, Dracaena is placed in the family Asparagaceae, subfamily Nolinoideae. It has also been placed in the former family Dracaenaceae.
Ceropegia dichotoma is a flowering plant in the genus Ceropegia (Apocynaceae). It is endemic to the Canary Islands, where it grows on Tenerife, El Hierro, La Gomera, and La Palma in the Tabaibal-Cardonal zone at up to about 600 m altitude. It was first described in 1812.

Dracaena cinnabari, the Socotra dragon tree or dragon blood tree, is a dragon tree native to the Socotra archipelago, part of Yemen, located in the Arabian Sea. It is so called due to the red sap that the trees produce.
Bystropogon is a genus of evergreen shrubs in the family Lamiaceae. It is native to the Canary Islands and Madeira in the western Atlantic Ocean. Allied to the Origanum and Thymus, the genus is characterized by tiny flowers in much-branched clusters, with plume-like sepals that elongate at the fruiting stage, giving the whole tip of each branch a fuzzy appearance. Stems are square in cross-section and leaves, arranged in opposite pairs, are aromatic when crushed.
