The Story
Plant Bio
Polypodium vulgare, common polypody, is a small creeping evergreen fern of the northern hemisphere, about a foot high and spreading to three feet. Leathery bright green triangular fronds four to twenty inches long rise singly from a scaly surface rhizome, and round orange-yellow spore clusters stud their undersides.
It is epiphytic in habit — in the wild it grows on mossy rock, walls and tree limbs rather than in soil, and that is exactly where it succeeds in a garden. Try it in the crevices of a shaded dry wall, where the creeping rhizome grips, rather than in a border where richer soil rots it. It holds its fronds through winter.

Planting
How to Grow

Pro Tip
The rhizome must sit on the surface — bury it as you would a border fern and it rots rather than creeping.
