- Description
-
Common Polypody is an epiphanic evergreen fern native to Africa and Eurasia that provides year-round interest. 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.
Its preference is for moist well-drained sandy soils in partial to full shade. 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.
Diseases, Insect Pests, and Other Plant Problems:
No significant diseases or pests. Watch for Florida Fern Caterpillar.
