Common name: sensitive fern, bead fern
Onoclea sensibilis: Its name comes from early American settlers who noticed that this fern was very sensitive to frost, the fronds dying quickly after the first cold spell in autumn. The brown sori cluster like beads on the upright fertile fronds and remain standing through winter. There are several in the Garden, especially in the Fern Dell and the Woodland Garden.
