The common polypody is a hardy fern of damp, shady places in woodlands. It also makes a good garden fern. It has ladder-like, leathery foliage with pimply undersides - these spots are the spores.

Ynghylch

The common polypody is a medium-sized fern that is characteristic of damp, shady gorges and banks in woodlands, as well as rocks, walls and mossy branches. It can also survive in quite dry conditions and is ideal for gardens - plant it in shade under trees, or on walls or gravelly areas for attractive cover.

Sut i'w hadnabod

There are three species of polypody, all of which look similar: fronds are made up of simple, finger-like leaflets coming out of the main stem, giving them a ladder-like appearance. The spore-bearing organs are small and round, and are found on the underside of the fronds; they range in colour from bright yellow to orange.

Dosbarthiad

Widespread.
