Athyrium felix-femina Dre's Dagger, also known as 'Crucio Cristata' is a fascinating form of Lady's Fern. She has a compact habit, only reaching 18" in height, with light green crested fronds. The pinnae on each frond create the most interesting criss cross branching pattern. Keep Ladyferns happy in moist fertile well drained soil. Excellent and unusual as a cut green, and lovely in the shade garden.
