| I say go for it... try using one of those common and cheap oncidiums. Not sure how your fireplace is set up but might need to use some tillandsia glue to attach the orchid to the stone. In terms of moisture, a horizontal flat stone (especially one with a nice little water catching indentation) would be a better choice than a vertical stone and it would help to have some sphagnum moss between the orchid and the stone...I recommend New Zealand over green. |
