Hard Shield-fern

Hard Shield-fern

In Norfolk, Hard Shield-fern, Polystichum aculeatum, grows on hedgebanks, on ditch banks (usually by hedges or in woodland) and on the woodland floor. Young plants are occasionally seen on walls, but there they rarely reach maturity. The plants are winter-green and as the surrounding vegetation dies back they become easier to spot.
