 Ostrich Fern (Matteuccia struthiopteris) on Alpine Hill (or Alpinarium). Sterile Fronds (The "Feathers"): The large, outer leaves have turned from green to a golden-bronze color. These are the "ostrich feathers" that give the plant its name. They are withering now and will soon collapse for the winter. Fertile Fronds (The Dark Spikes): In the very center, there are the dark brown, stiff, upright spikes. These are the spore-bearing fronds (sporophylls). Unlike the leafy outer fronds, these become woody and persist standing upright through the entire winter, often poking out through the snow.
