Dragon trees come from Tenerife and the Canary Islands, and it is said they are also found in Cape Verde, Madeira and parts of Morocco, so I wasn't expecting to find them in Portugal or Gibraltar. However, they do grow in these places and grow very well there, as I was to discover.
Dragon trees can be seen in a botanical garden in the centre of Lisbon in Portugal and also in parks and gardens in Gibraltar. The dragon trees in these locations were just as healthy and well-formed as most of their counterparts in Tenerife, though admittedly not as big as some of the very old trees found in the Canary Islands.

The dragon tree (Dracaena draco) is a weird plant, not really a tree, although it grows to tree-like proportions. It has spiky leaves that grow in rosettes and bears small white perfumed flowers that turn into orange-red berries as they ripen.

Dragon trees get their name because if cut they bleed a red sap known as Dragon’s Blood, and also because aerial roots that hang downward can resemble a dragon’s beard.
The dragon tree produces a mushroom-shaped head of branches that fan outwards. The many branches in these dragon tree crowns are said to be like the hundred heads of a dragon that the hero Hercules killed.

Dragon trees can grow for a very long time and the Drago Milenario that grows in Icod de los Vinos in Tenerife is said to be 1,000-years-old, though estimates put it more like somewhere between 250 and 650 years in age.
Whatever its age, the Drago Milenario is a majestic specimen and is the oldest dragon tree in the world. It has become a plant symbol of Tenerife and many tourists flock to see it in the Parque del Drago it stands in.
Dragon trees are very rare in the wild but are extensively cultivated in subtropical gardens and parks. They take a very long time to grow and only have a single trunk until the first time they flower when the tree produces side shoots from its crown. It can take 10 years before a dragon tree is big enough to flower and then branch.

The dragon tree has been classed as a medicinal herb because its sap is said to be good for strengthening the gums.
The Guanches, who were the people who lived in Tenerife before the Spanish Conquest made shields out of the trunk and held the dragon tree in great reverence.
Dragon tree berries have one or two seeds and can be germinated easily enough though they may take as much as a month before sprouting.
