Native Region: Statewide

Large, somewhat coarse fern which is good for rain gardens and bog gardens. Allow sufficient space. Can grow in very wet soils as long as there is adequate oxygen. Cannot tolerate sour clay or stagnant water and is sensitive to drought. Very aggressive with sufficient moisture so be cautious when planting. Drier soil will help keep it in check. Occurs naturally in wet woods and thickets and in moist soils along streams and springs. Common name comes from fact that its green fronds are sensitive to and suffer damage from first fall frost. Other common name comes from fact that the stalks of the fern are said to have a decorative appearance. Toxic and sometimes fatal to horses and livestock.
