Of the 10 native Californian species of Selaginella, Selaginella oregana is the most distinct in that it occurs as an epiphyte whereas all other species are strictly terrestrial. Perhaps it is more closely allied to the ancestry of the species that arose from epiphytic lycophytes as S. oregana often has vegetative strobili along the course of its pendant stems.

While naturally occurring as an epiphytic and occasionally as a terrestrial, the species can be easily grown as a pot plant.
