Phalaenopsis, or moth orchids are epiphytic in the wild. Basically that means that they grow above ground in trees, rather than in soil on the ground. That is why the roots are greenish, and like to be exposed to the light, through a clear plastic, or glass pot. Although I have been told not to cut off the flowering shoots on moth orchids when they finish, some of mine turned brown and died this year, so I had to cut them off. As lilwead says, if you cut the stem just above the node where the last flower was, the stem should remain alive, and hopefully produce new flowers in a few months.
