Summary

Polypodium scouleri, commonly known as Leathery Polypody, Scouler’s Polypody, Coast Polypody, or Leather-Leaf Fern, is an evergreen fern native to the coastal fog belt of western North America, from British Columbia to Guadalupe Island off Baja California. It thrives in the understory of coastal coniferous forests, often on rocky outcrops and cliffs, as well as in the sheltered nooks of beach dunes. This fern is well-adapted to its native habitat, where it benefits from the high humidity and moisture provided by heavy fogs and sea spray.

Leathery Polypody has a distinctive appearance with its leathery, dark green fronds that can reach up to 50 cm long. The fronds are pinnatifid with a tough texture, contributing to its common name. It does not produce notable flowers or seeds, as it reproduces via spores. This fern is valued in cultivation for its hardiness and its ability to thrive in coastal gardens where other plants may struggle with salt spray and wind. It is used for ground cover, in rock gardens, and as an accent in shaded areas. Leathery Polypody requires minimal maintenance, making it an attractive choice for gardeners. It prefers part shade but can tolerate full sun in cooler, coastal climates. While it can handle medium to high water conditions, it is also somewhat drought-tolerant once established. It is important to plant it in well-draining soil to prevent root rot.CC BY-SA 4.0
