Description
The hay-scented fern is an attractive, delicate-looking native fern that forms lush, expansive colonies across forest floors and rocky clearings. Its bright yellow-green fronds add vibrant color to the understory from spring through summer. When bruised, crushed, or drying out, the fronds emit a distinct, pleasant aroma reminiscent of freshly mown hay due to the release of coumarin. As autumn approaches, the green foliage transforms into a brilliant golden-yellow before dying back for the winter.
Habitat
Thrives in moist to dry acidic soils, open woods, rocky slopes, pastures, and cleared areas; frequently forms dense colonies in partial shade to full sun.
Native Range
Native to eastern North America, ranging from Nova Scotia south to Georgia, and west to Arkansas and Minnesota.
