Wall flowers in Weardale

Dry stone walls, and old stone walls held together with mortar, acquire a flora of resilient species that thrive in their damp crevices. In Weardale these vertical gardens are at their best from mid-May to early June, before conditions become too dry.

Fairy foxglove Erinus alpinus covers large areas of old walls in Stanhope.

Ferns colonise walls too, but usually on the side that's shaded from the sun. This is brittle bladder fern Cystopteris fragilis, growing  in the wall around St. John's Chapel churchyard in Weardale.
