Um, is it just me, or are your flowers playing music? Mess with your friends' heads and provide music on your patio with StereoStone's Hanging Planter Speaker.
This version retails for $149.95 and is powered by running a cable from your stereo receiver to the planter--so that means you're likely to need a very long cable to do it, but the planter can stay out in any weather. The speaker is entirely sealed, but it also provides drainage for the plant on top, comes with a two year warranty, and is made entirely in the U.S.
