Common Polypody

Polypodium vulgare (pol-ee-POH-dee-um vul-GAR-ee)

Family: Polypodiaceae Non-native Herbaceous

Common polypody is an epiphytic, evergreen fern in the polypody family (Polypodiaceae). It is native to Europe, Asia and Africa. The species epithet is Latin for “common.” In a garden setting, its preference is for moist, well-drained sandy, humus-rich or loamy soils, in partial to full shade. As an epiphyte, it gets nutrition from the rain and falling debris. Like most epiphytes, it can tolerate periods of dryness. The fronds grow from a horizontal rhizome and can be found in old walls, cracks in rocks, the bases of trees, in rocky undergrowth and on tree limbs. The leathery green fronds can grow to 12 inches long and have large sori on the undersides giving the upper side a bumpy appearance. It is grown for the foliage and can be used under shrubs and trees, in the front border of a shade garden, as an evergreen ground cover, on slopes or in a rock garden. The common polypody provides year-round interest. Diseases, Insect Pests, and Other Plant Problems: No significant diseases or pests. Watch for Florida Fern Caterpillar.
