The most eco-friendly option would be to skip the indoor trees and plant some real ones out in nature, where they belong. You can always get a houseplant and put a little ornament on it. The "get one, plant one" approach is also very popular if you want to take an extra step for sustainability. If you bring home a tree, plant one or more with us to benefit nature. You’ll even get a festive tree certificate. Take it a step further and plant trees for the whole family!
