Dracaena draco is a tree native to the Canary Islands, slow growing, and can reach a great age. The oldest known tree is growing in northwest Tenerife and is believed to be up to 650 years old. The name comes from the red snap like dragons blood. The ancient Egyptians used it for embalming the dead and more recently it has been used to make varnish for violins and as a wood stain. Only hardy to around -5°C but worth trying in a sheltered location. Make sure that any containers have good drainage with a gritty compost. Water infrequently, allowing the compost to dry out slightly between watering.
