Adiantum capillus-veneris (Southern maidenhair fern)
Marcus, Joseph A.
This plant has specific growing requirements that must be met to be successful in a garden setting. Though it lacks the fan-like pattern of Northern maidenhair, the fine, lacy foliage of Southern maidenhair has the same a graceful, delicate character. This fern grows from 6 inches to 1 foot in height; its fronds arising in clusters from creeping rhizomes.

Listed as an endangered species in North Carolina (known as southern maidenhair-fern there) and threatened in Kentucky (known as venus hair fern there). Mostly found in the lower half of the U.S.and some parts of the tropics, the only Canadian site is near Fairmont Hot Springs, B.C.
