Epiphytes



An epiphyte is any plant which grows on another plant but does not directly harm that plant. This usually refers to plants such as orchids or bromeliads which grow on tree branches high in forest canopies, but the same pattern also occurs in the aquatic world where plants fight for precious light which grows dim as the water deepens. An epiphyte is different from a parasite in that a parasite harms it's host by smothering it or stealing nutrients from it. A true epiphyte uses it's host merely as a support. Aquatic plants such as Java fern (Microsorium pteropus) and various Anubias species, as well as Java moss (Antipyretica) can be used on driftwood and rocks to soften and beautify a scene. Java fern is especially suited to growth on driftwood or rocks, as it's threadlike roots grasp tight and send out lush green fronds which grow densely even in minimal lighting. In a paludarium where rocks or roots extend out of the water, terrestrial epiphytes such as orchids, ferns, bromeliads, vines or moss may be used. These will obtain their moisture from the humidity evaporating from the water's surface. They may need additional watering, depending on the humidity level. Some vines such as Pathos or some Philodendron species will grow roots into the water and climb up a piece of wood or rock.
