What the? Yes, it really is a planted piano. There were also planters disguised as drums used as containers for a vine working its way up to a planted roof. And a guitar neck holding back some potentially unruly grass. All of this along a very busy street in North Portland. There is even a small pond. Stopping to take these pictures I finally got it! The plantings are next to Ethos Music Center, a nonprofit organization dedicated to the promotion of music and music-based education for youth in under served communities. Looks like they are also promoting fun gardening.
