Deer, wild turkey, and other animals eat the foliage of cut-leaf grape fern, especially in spring and fall, when these evergreen plants are most noticeable. Wagner Dr. Rintz found, photographed, did germination work and more for this work. One part of the leaf, the trophophore, is sterile and fernlike; the other, the sporophore, is fertile and carries the clusters of sporangia or spore cases. Another stalk grows upward from the base and bears yellowish spore cases that resemble tiny grape bunches. The diversity of nonwoody vascular plants is staggering!

During the summer, typically in late June, a new leaf begins to emerge and unfold. The “troph-” of trophophore refers to nutrition (because the leaves conduct photosynthesis, which makes food for the plant). oneidense (Gilbert) Farw. The vegetative portion of the leaf (compound, fernlike) and the fertile portion of the leaf (spore-bearing, resembling miniature clusters of grapes) both actually arise from a common stalk, but the split is so low to the ground they often appear separate. Cut-leaf grape fern is a perennial, evergreen fern with a single, two-parted leaf that arises from the ground with what looks like two separate stalks into a vegetative portion and a fertile portion.
