It is green at Christmas time as the common name suggests. The stocking shape of the pinnae also suggests Christmas.Crosiers (young fiddleheads) in spring are silvery and scaled. Sori appear on the undersides of the pinnae only at the ends (last 1/3) of the fronds.Christmas ferns are asymmetrical with a fine texture and have a moderately dense crown. The evergreen fronds provide good winter interest for the landscape.This fern does not spread but the clumps increase in size over time.
