Hay Scented Fern

Dennstaedtia

Dennstaedtia punctilobula ( Hay Scented Fern )
A beautiful, rhizomatous, fast spreading deciduous Fern, reaching up to 3 x 8 feet, that is native to open woods and sandy meadows in eastern North America ( from southeast Missouri to southern Wisconsin to Jackson, Michigan to Lions Head, Ontario to Haliburton, Ontario to southern Quebec to Newfoundland; south to Arkansas to northern Georgia to North Carolina ). It is critically endangered in Michigan with a single population in Jackson County. It is also endangered in Wisconsin, Indiana, Illinois, Missouri and Arkansas.
The thin textured, hairy fronds, up to 52 x 12 ( rarely over 36 ) inches, are oblong in outline and bright green, turning to yellow in autumn.
It can spread invasively but is also an excellent groundcover when used over large areas such as a woodland understory.
Hardy zones 2 to 8, in partial to full shade on moist, acidic soil. Tolerates sun.
Deer resistant.

Dennstaedtia hirsuta ( Asian Hay Scented Fern )
Very similar to D. punctilobula, except that it is native to eastern Asia rather than North America.
Exact hardiness is unknown however it is likely to thrive in most temperate climate regions.
