I want to assume that by ‘’Co dependent plants’’, you mean plants that depend on other plants.

If so then, you are looking for Epiphytes

An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it.

An epiphytic organism that is not a plant is sometimes called an Epibiont

Example of Epiphytes includes:

1. many mosses, liverworts, lichens, and algae found in the in the temperate zone
2. or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads)

Hope this answers your question..

Non è codipendenza, ma un certo numero di piante crescono meglio se piantate in mezzo ad altre invece che isolate.

Una di queste è il sandalo qui sull'isola di Hawaii.
