Healthy noble firs on a Washington farm. Did you know that most Christmas trees are grown on farms? Or that live trees have been carefully bred for smell, color and needle retention (they’re usually cut to make that perfect conical shape, of course). Gary Chastagner, a plant biologist at Washington State University, studies firs, pines and other conifers to see how plant genes can help create the “perfect holiday tree.” Of the 35 million trees harvested worldwide each year, one-third come from Washington and Oregon states. And, unlike artificial trees, the real ones can be recycled.
