By filling a room with green houseplants, you're not simply choosing a single color. You're choosing a thousand shades. Forest green. Kelly green. Jungle green. The possibilities are endless. Aloe vera, the healing succulent that protects the skin from sunburn. Or dieffenbachia, the humidity-loving house plant that's easy to care for. For a touch of autumn in your green houseplants, try a croton, whose evergreen leaves can be variegated with orange, yellow, and red. No matter which green indoor houseplants you choose, your indoor houseplants will thank you with a thousand shades of green.
