When plants self-seed they often find perfect niches in which to set up home. In a garden recently we found young ferns which had found just such places, but I suppose they self-spore rather than self-seed. All around the edge of a curling path edged with silver birch trunks little ferns were establishing themselves.
After putting these photos into the blog I had to go out with the camera into our own garden to see what our ferns were getting up to.
Having started this post and saved it to finish later we went for a woodland walk and discovered two of our native ferns growing happily in the dappled shade.
