I had the good fortune to be able to visit this increadible tree back in 1994. They say that this tree (Draceana draco) is over 1000 years old. It is located in the Canary Islands, on the Island of Tenerife in the town of Icod. These Dragon trees (sometimes called Dragon's blood trees for the red color of their sap) grow wild only in the Canary Islands but have been planted in many other places such as California, Australia, Spain, etc. (in places where the temps don't go sub freezing).
