Dracaena fragrans, or Dragon Tree Cintho, is a shrub with leaves forming as rosettes on stems and at the tip of the plant.  It has very long sword-shaped leaves.  The variety "Cintho" has attractively variegated foliage with fine yellow stripes along the centres of the leaves (the reverse of the pattern of variegation found on the variety "Golden Coast"). The Dragon Tree makes a perfect floor-standing houseplant for your home.

In the wild, they can grow up to 3m, in height, and are sometimes used for hedging.  As houseplants, they are typically much smaller. Dracaena fragrans is notable for its highly scented flowers (hence 'fragrans', meaning fragrant), and you may be lucky to get flowers on yours.  They're not especially attractive, but have a delightful smell.
