Woodwardia radicans flourishing.
Another plant is was exciting to see growing effectively wild in Ireland was the giant chain fern, Woodwardia Radicans.
While this grows in protected London gardens, where it gets enough moisture and humidity, it is far happier and grows to truly impressive size in damp coastal Kerry. The fronds can happily reach six foot in length and cascade down banks, which looks really impressive. It seems to propagate both by bulbils from the tips of the fronds, and also by spores.
