The first choice is habit. New York fern is the tapering woodland fern of eastern shade, about 1 to 2 feet. [1] marsh fern is the wet-ground fern. It takes more sun than New York fern if the soil stays wet, and it is not a plant for standing water. [2] southern shield fern is the larger southern clump, 2 to 4 feet, for heat and humidity. Fronds bronze before they die back. [3] Read the Latin on the tag before you buy, because shop names still say wood fern and maidenhair.
Which maiden fern should I plant?
Buy New York fern for a tapering woodland clump, marsh fern for a wet rain-garden strip, or southern shield fern for a 2 to 4 ft southern groundcover.
Is New York fern a marsh fern?
No. New York fern tapers at both ends in moist woods. Marsh fern wants wet ground and will take more sun if that ground stays wet.
Browse by kind
Match the habit, then pick that kind. Care for the clump you already have on How to Grow Maiden Fern.
New York ferns
New York fern is the eastern woodland kind. The blade is widest in the middle and tapers to tiny leaflets at both ends, about 1 to 2 feet tall. It is not hay-scented fern.
Marsh ferns
marsh fern is the wet-ground kind, about 1 to 2.5 feet, with the middle pinnae widest. It takes full sun if the soil stays wet, and it is not a dry-woods New York fern.
Southern shield ferns
southern shield fern is the southern groundcover, with arching fronds 2 to 4 feet long. It handles heat and humidity, then turns bronze before it sheds. Shop tags also say southern maiden fern or river fern.
Southern shield fern is also sold as wood fern east of central Texas and as river fern farther west. That tag is still southern shield fern, not Dryopteris. [4] Set the clump you picked on Planting Maiden Fern.
If you wanted the tapering woodland clump, buy New York fern — marsh fern is the one for wet sun, and southern shield fern is the 2 to 4 ft southern groundcover.
