An excellent deciduous native fern which may reach 6’ tall. Spreading fan-like from their base, the fronds each form a diamond of feathery foliage.

Select a sheltered spot to protect the delicate, yellow-green herbage from wind damage. Lady Fern likes moist, even boggy, soil and shade.

Beautiful at the back of a border, the wonderful large fronds of Lady Fern are tall enough for underplanting with smaller woodland perennials such as Wild Ginger (Asarum caudatum), Bunchberry (Cornus unalaschkensis) or Western Trillium (Trillium ovatum ssp. ovatum).

Found growing across North America, Lady Fern is considered threatened in both New York and Florida. It is hardy from USDA zones 4-8. Native Americans ate the “fiddleheads” of this species.
