Polypody is widespread and easy to see in the winter
Polypody is widespread and easy to see in the winter found on mossy oak branches and trunks, especially on older trees which have less acidic bark than the younger trees, the bark of which contains tannin which was used for treating animal hides in leather production.
This fern requires very damp conditions to thrive, and in our western Atlantic climate, it does very well.
It has hidden, creeping rhizomes which hug the bark of the tree in the `soil’ created under the mosses.
They reproduce using spores, tiny clusters of which can be found under the leaves.
