Polystichum aculeatum
The hard shield fern is a lovely green plant that likes to grow in shady places. Its leaves are shaped like shields, making it look very special in the forest!
生息地: Forests
The hard shield fern has shiny, dark green fronds that are stiff, leathery, and arch outwards. Its individual leaflets have distinctive ear-like lobes near their stalks, resembling tiny shields, giving the fern its common name. The underside of its fronds often reveals small, brown spore cases.
