In a previous post, I discussed the different growth habitats of orchids, including Epiphytes and Terrestrials.  One type i did not discuss are Lithophytes.   A lithophytic orchid is an ephiphyte that grows on rocks, or extremely rocky terrain.  Lthophytes, like epiphytes, obtain their nutrients from the air, rain, decaying matter that has accumulated around the rocks & roots. 

Vandas are sometimes grown in wooden baskets filled with lavarocks, thus being grown as lithophytes.  These plants need constant humidity, daily watering with warm water, and a breeze to take away any excess moisture from the rocks.  They are grown successfully by home growers in South Florida and along the Gulf Coast where these conditions naturally exist. They only need to be brought inside during the coldest weeks or months of the winter.
