A beautiful variety of the hardy Dracaena, the Marginata TriColor has bright green and pink foliage and is a great beginner houseplant. They can do well in low light but want medium indirect light to maintain their coloring. Never put in full sun - their leaves burn easily. Avoid overwatering your Dracaena - only water when top half of soil is dried out.  Also prefer distilled water or tap water that's been left out overnight. Browning tips on the leaves indicate overwatering or a reaction to chemicals in tap water.
