On the West Coast between British Columbia and Mexico, the largest native fern might be the giant chain fern, Woodwardia fimbriata. In sheltered and damp coastal forests, it can get taller than six feet, although it is typically about three feet tall and wide in home gardens. The lightly colored and almost yellowish green fronds generally stand upright and flare outward from the center. The foliage is doubly lobed and lacy, but quite substantial. The thick rhizomes spread rather slowly. Established plants are remarkably resilient. They can tolerate almost full sun exposure if watered enough. Those in partial shade can tolerate lapses of watering. However, they do not recover too readily from relocation or division.
