Get a free citrus tree to plant in a public space or your own backyard thanks to the artist collaborative Fallen Fruit. Just show up to One Colorado in Pasadena between 7 and 8pm (6pm if you RSVP to info@fallenfruit.org by Wednesday) and you can walk away with one of over 50 three-year-old citrus trees. You'll be asked to sign an adoption form promising to care for the tree—Fallen Fruit will provide planting instructions and caretaking tips. Limit one tree per family.
