General Culture:

Best grown in moist, rich, humusy, acidic, medium wet loams in part shade to full shade. With consistent moisture, it tolerates full sun. Also tolerates a wide range of soils, including poor rocky soils and, once well established, dry soils. Also tolerates full shade. Spreads aggresively by rhizomes to form colonies.

Noteworthy Characteristics:

When brushed with a hand, crushed or bruised, the fronds of hay-scented fern release a fragrance reminiscent of fresh mown hay. This is a deciduous fern that is native to open woods and wooded banks in the eastern and midwestern U. S. Although uncommon in Missouri, it is quite common, almost to the point of being considered weedy, in some parts of its range such as New England. It typically grows to 2?tall and features lacy, narrow-triangular, erect to arching, yellowish green fronds (to 30?long). Fronds turn yellow in fall. Marginal sori are surrounded by cup-shaped indusia, hence the sometimes used common name of cup fern for plants in the genus Dennstaedtia. Genus honors A. W. Dennstaedt, 18th century German botanist.

Problems:

No serious insect or disease problems. In hot summer climates, fronds tend to decline by late summer.

Uses:

Good fern for naturalizing in woodland areas, shade gardens, cottage gardens or wild areas.
