No ferns can tolerate lengthy dry spells and stay healthy looking.
On the other hand, some of them can adapt to competition from neighbouring plants and grow at the base of a hedge, for instance, like male fern (Dryopteris filix-mas). Our common polypody, or rock polypody, (Polypodium virginianum) can grow on rocky ledges similar to its well-drained natural habitat, and is also somewhat drought tolerant.
