Family

Dennstaedtiaceae

Botanical Name

DENNSTAEDTIA punctilobula

Plant Common Name

Hayscented Fern

General Description

This rapidly spreading, sun-tolerant fern inhabits clearings and open woodlands in eastern and central North America, often forming large colonies. Its common name refers to the hay-like scent of its lacy, yellow-green fronds.

Light green fiddleheads arise from slender underground rhizomes in spring, soon unfurling into upright, triangular fronds. The bipinnately compound fronds are divided into approximately 20 pairs of segments (pinnae) which are themselves divided into pinnules. The frond's central stem (rachis) is yellow-brown and slightly hairy. Tiny round spore cases (sori) are borne at the pinnules' margins in summer. The fronds wither and turn bronze-brown in fall, their shriveled remains often persisting until spring.

Grow hayscented fern in humus-rich, acidic soil in full to partial sun. Plantings in full sun require moist soil. Although not well suited to formal landscapes, this aggressively spreading fern does have merit as a groundcover for naturalistic shade gardens. It contains compounds that render it unpalatable to herbivores and that inhibit the growth of neighboring plants.
