Dragon blood

The dragon tree (Dracaena draco, Dracaenaceae), a species endemic to Macaronesia, is a mythical tree in more than one way. First by its scientific name, doubly evocative of its legendary origin.

Indeed, Dracaena comes from the Greek drakaira, designating the female dragon, and draco is the Latin name for the dragon.

The dragon tree was born from the blood spilled by Ladon, the hundred-headed dragon, slain by Hercules during one of his famous labors. This monster was responsible for guarding the entrance to the Garden of the Hesperides, a place located on an archipelago considered by the Ancients to be the western “limit” of the world and which would correspond to the current Canary Islands.

But the basis of this fantastic origin and of this name comes from the peculiarities of its sap, a resin which oxidizes and dries in the open air, taking a blood red tint.
