Illustration of Dracaena or dragon tree leaves The bark of some Dracaena or dragon trees oozes out a kind of resin called\" dragon blood because it becomes red and brittle when it dries. The elegant Dracaena exudes exoticism, with its false air of a small palm tree, its solid trunk and its green, yellow, gold or even red leaves, thin or large, plain or striated, which will make you travel to distant destinations in the azure seas. This illustration is surrounded by borders imitating ancient ribbons.
