Trees offer a stable home for the epiphytic orchid where it can utilize the trees' resources to feed. The epiphytic orchid will not establish itself within the tree. The tree provides an abundance of flesh on its bark and branches whereby the epiphytic orchid can flourish. The compost that builds up around the trees' leaves and roots serve as nourishment for the orchid. During periods of drought and flood, the epiphytic orchid's root system can help maintain its homeostasis. The root's interior is made up of a strong, sinewy core covered with a porous material that easily retains water. When there's a drought, the whitish sponge-like material turns a very light green. When there's rainfall, it drinks up the water. As the rest of the plant desiccates, the stored water source will be distributed where needed. Moreover, epiphytic orchids are known to grow on the face of rock structures. When clung to a rock or tree, it strategically positions itself to bathe in fresh air and light that has been filtered through the trees.
