Even if your poinsettia has lost all its leaves, if you move it to a sunny, draft-free location it will make a comeback.
Native to tropical parts of Mexico and Central America, poinsettias were well-known to the Aztecs before being brought north by Joel Poinsett, the American Ambassador to Mexico. Today, with their lush green and brilliant red, poinsettias are the quintessential Christmas plant — and post-Christmas compost. But it needn't be! Poinsettias make great houseplants, and with a little diligence you can even get them to rebloom next year.
