Hello I was wondering if you could help I would really like to know what this little fern is. Last year I litter picked a beer bottle from the moat around a medieval manor site next to where I live. I was about to put the bottle in the recycling when I spotted there was something growing in it. At first I thought it was just moss but when I managed to get it out there was a tiny fern too. It survived the removal from the bottle but has remained very small. The longest fond is about 2cm, so it has been quite difficult to photograph. I have looked at the back of the leaves but can’t see any markings and I am sorry the back of the leaf photos aren’t very good.
I have two self-sown Cyrtomium fortunei, 4-5 years old that appeared on my tufa rockery. Since being relocated 2 years ago to an established shady raised bed that is filled with enriched (multi-purpose compost) London soil they have produced sparsely bladed fronds with contorted pinnae.
Is this disease or am I growing up a rather ugly cultivar?
If disease, can it be treated, or would euthanasia be a better solution? If it’s a cultivar, does it have a name?
Hello this fern is growing out of a sandstone cliff down a sheltered alley in Hastings. No direct sunlight. Photo taken from fire escape, I couldn’t Get closer than this would need very long ladder or scaffolding. I can’t find anything similar in identification pictures. The fronds are about 3 feet long.
