The dragon's blood plant (Dracaena draco) is not the friendliest or most beautiful of houseplants. But it has the single most important quality for your indoors foliage—it is tough beyond all measure. It has somewhat severe, stiffly pointed leaves that end in something resembling a spike. The leaves are solidly green, and the plant will grow to a height of 3 or 4 feet indoors.

The dragon's blood name comes from the fact that it exudes reddish resin from wounds and nicks. As a point of interest, it is said that this resin was used as a wood dye to stain the famous Stradivarius violins. It is a member of the agave family and is related to the yucca and century plant.

Native to the Canary Islands, these plants appreciate excellent drainage—the quickest way to kill it is to waterlog the roots. Watch out for leaf-tip browning, which can be corrected by using non-fluoridated water.
