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. The dragon blood tree has a unique and strange appearance, with an upturned, densely-packed crown having the shape of an uprightly held umbrella. This evergreen species is named after its dark red resin, which is known as "dragon's blood".

According to legend, the first dragon blood tree was created from the blood of a dragon that was wounded when it fought an elephant. Like the unfortunate dragon, the tree secretes its resin when it's injured. In ancient times the resin was believed to have magical and medicinal properties. People used it as a pigment for art, a dye, and medicine. Dragon's blood is still used for these purposes today.
