Basic Description

A quite majestic fern, growing up to 4 feet tall with a graceful vase-shaped habit. It resembles the cinnamon fern except in the way each frond is ‘interrupted’ in the middle by the fertile area (sporangia) which are greenish-brown and much smaller than the green leaf blades (pinnae) above and below this section. It also has a distinctive yellow or golden-brown fall color. A definite ‘conversation’ plant! Attracts songbirds such as wood thrush and ovenbird.
