There are 100 species of vanilla orchid, a vine which can get up to 300 feet in length, but in home cultivation the plant will likely only grow a fraction of its potential. As a climbing plant, vanilla bean orchids will need a support, such as a sturdy stake or a wall, to climb on. The roots that emerge from the vining stem, which are called air roots, attach to the support to climb up and over it. These orchids require almost no pruning, unless the plant has become too large.
