The Dragon Tree is an attractive and interesting succulent tree that is commonly used as a house plant, however, if grown outdoors in a frost free climate it will slowly grow to a massive and broad tree that is 25 feet tall and 25 feet wide and with great age, even larger. The terminal ends of the thick branches hold clusters of 2 foot long by 1 1/2 inch wide pliable sword-shaped blue-green leaves. When the bark is cut or bruised the sap flows as a reddish colored resin known as Dragon's blood. The sap is used as coloring matter for varnishes, tinctures and plasters.
