Dracaena cinnabari, the Socotra Dragon Tree or Dragon Blood Tree, is a Dragon Tree native to the Socotra archipelago in the Indian Ocean. It is so called due to the red sap that the trees produce. Dracaena Cinnabari by Jan Vandorpe.
Buddha was said to sit under a tree of enlightenment, learning about himself and being tested by demons. I think that just sitting under a tree like this would be enough of a spiritual experience for me.
