(Award of Garden Merit) Family Onocleaceae
Originating from North America and Japan
Onoclea sensibilis derives its common names because a) fronds wilt at the first hint of frost, or if picked. Don't worry because its rootstock is hardy to minus 30 degrees centigrade. b) It produces upright fertile fronds, very different to the infertile green fronds that are covered in small, bead-like sori.
Grow in sun or shade in moist soil, by water or in damp woodland.
