Is it generally ok for a plant's health if it is placed on top of a wall air conditioning unit? It doesn't get very hot, but it does vibrate. Weight will reduces this vibration. I am considering placing a small potted palm and/or a lucky bamboo but I don't want to do harm! I've nowhere else in the little alcove for any plants and can't drill into the wall. Please help!

The main concern here is not so much the vibrating but the draft or cold air come from the A/C itself (provided this will be indoors). This can oftentimes be detrimental to houseplants. If you have a cool-hardy plant, this may not be a big issue. If it's outdoors, then the opposite may occur--too much warm air coming from the unit.
