Considering this, are all orchids epiphytes?
Approximately 70 percent of all orchids are epiphytes, plants that grow on other plants. Their root systems are not as extensive as those of terrestrial orchids but are highly efficient at quickly absorbing moisture and nutrients. Epiphytic orchids are not parasites; they derive no nutrients directly from their hosts.
Subsequently, question is, are phalaenopsis orchids epiphytic?
Phalaenopsis are epiphytic plants. The roots on epiphytic orchids are covered with a spongy tissue called velamen. Orchids require more air than terrestrial plants around their roots.
