Hi there,

Does anybody recognise these ferns? I noticed them growing on my workplace wall for the first time this year & would love to know what they are!

Thanks Smiling

They look like Button Ferns (Pellaea rotundifolia)

Here are our database entries for the two possibilities mentioned where you will find other members photos for comparison. They both look a lot alike.
Button Fern (Pellaea rotundifolia)
Maidenhair spleenwort (Asplenium trichomanes)

Asplenium trichomanes...... commonly known as the maidenhair spleenwort.
Very common in walls UK. They love the old lime mortar.

How do homeowners deal with this? It's beautiful, but I can imagine that it's very good for the mortar.

...another problem, another list! David

Asplenium makes sense Silversurfer. Maidenhairs do love limestone. Thumbs up

In Bermuda they grow beautifully out of the walls made of "Bermuda stone" which is really just compacted coral. They would probably also grow out of the houses if it weren't for the paint.

It is a very small, very slow growing dwarf fern.
As far as I am aware it never causes any sort of problem to old walls.
Normally old garden walls...not walls of houses.
I love to see it.

Wow thank you all so much. I need to find out if this wall is original, and if so it would have survive the Blitz. The ferns are so lovely at the entrance to the farm (Surrey Docks Farm in London). Thank again!

If it survived the blitz, it won't even sneeze at a pretty little fern.
