The fern has spores on the bottom of the fronds, contained in sori. Sori can be found aligned in rows on the underside of fertile fronds. They start as yellow, but as they mature, they turn brown and split. [13] The fern sporulates in summer and early fall. Rhizome sections are also viable offspring and can root themselves in new medium.
The sori, producing the spores, are large and round. Like many tree ferns, it features a "skirt" of dead leaves that do not drop off the crown and form a barrier for parasitic climbing plants.

The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase.
"Plant the divisions to the same depth as the original plant, so the crown isn't buried too deep or too shallow," says Irish-Hanson. Burying the crown too deep can cause the fern to rot, but ...
Annual autumn leaf drop in temperate zones is caused by the abscission of the mature leaves from the growth season in response to the approach of cold winter weather. Abscission (from Latin ab- 'away' and scindere 'to cut') is the shedding of various parts of an organism, such as a plant dropping a leaf, fruit, flower, or seed.
While these plants are relatively low maintenance, it’s not unusual for peace lily leaves to turn yellow here and there due to stress, pests, or other issues. This guide explains the most common ...
Since it is a fern, P. glycyrrhiza reproduces by spores; the spores form in two rows of sori, which look like large spots on the undersides of the leaves. The sori range in color from yellow to orange to brown. Plants that are not thriving may have no sori or the sori may be patchy and will not appear in neat rows.
Pentagramma triangularis, commonly known as the gold fern or the goldback fern, is a species of fern in the family Pteridaceae, native to Western North America, with highest abundance in the state of California. [2] Its common name "goldback" refers to the light yellow color of the fern's protective coating which inhibits moisture loss.
