About Coffee Fern (Pellaea andromedifolia) Pellaea andromedifolia is a species of cliff brake fern known by the common name coffee fern. It is native to California in the United States and Baja California in Mexico. This plant does not have the immediately recognizable sharply pointed leaflets on its fronds that many other ferns have. Its leaves bear rounded or oval-shaped segments widely spaced along the rachis. Each segment may curl under along its edges. The leaves are green when new, then turn red, purplish, or brown. Some individuals of this species are diploid and reproduce sexually, while some are triploid or tetraploid and reproduce by apogamy (growth of a plant from a gamete without fertilization).
