  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Sep 21, 2018 8:55 AM concerning plant:
    Cinnamon Fern is a common species in swamps and wet places in such areas all over the Northern Hemisphere. It is sold by larger, diverse conventional nurseries and native plant nurseries, but it is uncommon in most landscapes and gardens, even though it is such a pretty plant. Most of the gardening public does not know it. It does need a constantly moist or draining wet soil to do well. It bears shorter, upright fertile fronds that begin as green but turn cinnamon-colored when mature as the spores ripen in late spring. The longer sterile fronds of about 3 to 4 feet long are of a thick texture and turn a nice golden color in the fall.
