Maidenhair Spleenwort. We love common names. We must dig out our 15th century Herbal and read up on how to properly decoct this sweet little fern for afflicting humors of the spleen. Or we can just grow it in a gritty well-drained shaded rock garden and enjoy its evergreen delicate appearance which belies its rugged constitution. This little fern grows throughout the northern part of the northern hemisphere and just has a small foothold in our North Cascades. One of our favorite sights of this fern was when we did the Coast to Coast walk in northern England in the epic rainy summer of 2012 and we walked close to 200 miles through the Lakes District and Yorkshire Dales and Moors. We saw this growing everywhere naturalized on old stone walls, stone bridges and stone buildings. Very attractive and a clue to its drainage preferences.
