Athyrium Filix Femina Frizelliae
Tatting fern. In this fascinating variant of our native lady fern the pinnae are reduced to small circular lobes all along the length of the frond. Height 15-25cm. Best in damp semi-shade, but can take drier sites than most Athyrium filix-femina varieties on account of it losing less water than fuller fronded varieties. Because each frond is essentially linear, this is a very distinctive variety, having more the outline of a grass than a fern.
