CopyrightNational Gardening Association. For questions regarding this web site, contact Webmaster Plant-Plant Relationships Many interesting plant to plant relationships exist, covering the spectrum from mutually beneficial to wholly parasitic. An example of a beneficial, plant-plant relationship familiar to many gardeners is the "Three Sisters Garden. The corn plants grew straight and tall, giving the pole beans something to climb on.

The beans, since they are legumes, contributed nitrogen to the soil. And the pumpkins shaded out competing weeds.
And even something as simple as the relationship of a tree to the groundcover beneath it can be considered a beneficial, plant-plant relationship. The tree casts shade, providing habitat for a shade-loving groundcover, and the groundcover in turn keeps more deep-rooted and competitive grasses at bay. One interesting group of plants are the epiphytes. Relatively rare in temperate regions, epiphytes are quite common in tropical rainforests. An epiphyte is a plant that grows on another plant, neither harming nor helping it.
For example, mosses can be epiphytic, growing harmlessly on tree trunks. More exclusively epiphytic plants are the bromeliads and some orchids.
Epiphytes further influence rainforest biodiversity by supporting the survival of other tropical species. For instance, bromeliads, which have long overlapping leaves that form bowls, collect water that provides habitat for animals such as snails, frogs, and worms. When animals trapped in the tanks die, they decompose, providing the plant with an additional source of nutrients.
Epiphytes also support a variety of birds and insectswhich serve as the plants' primary pollinators. As a result, the rainforest canopy is literally buzzing with life, with animals such as hummingbirds, beetles, bees, and moths flitting among their preferred epiphytes, sipping nectar and transferring pollen from plant to plant.
Although much is known about epiphytes, scientists are working to find new ways to explore life in the rainforest canopy, suggesting that more will be revealed. The sheer number of different types of plants that live epiphytic lifestyles further suggests that new species of not only plants but the animals that visit them are awaiting discovery.
