Dracaena draco- Dracaena draco, also known as the dragon tree, is a tree endemic to the arid, rocky mountain ranges of the Canary Islands, Madeira, and Cape Verde. Though the dragon tree is commonly cultivated as a houseplant and garden specimen, there are very few naturally-occurring individuals remaining in its narrow ecological range. The dark red sap of Dracaena draco was regarded for centuries in European legends as ‰ÛÏthe blood of dragons‰Û�, and was often used for its supposed magical and medicinal qualities. This resin is still used today to produce incense and varnishes used to stain and polish wood.
