Shady evergreen perennial please?

We have several large green ferns, which come up every year.
They grow under a large Camila tree and also a crab apple tree.

In the the same area, we also have a Rose of Sharon ( St John's Wort) bush.
Which has lovely bright yellow flowers and seems to thrive quite well in the shade.

Ps it may not be shade that is the issue, but in fact the the lack of water and nutrients in the soil due to the crab apple tree.

I agree with Cherry - British fern(s) might be good. But do your research first - there are lots to choose from.

Lamium are ground covering plants, related to nettles, but not stinging. There’s quite a variety with variegated leaves. They were one of the few things that grew under our old oak tree.

Vinca Minor, hardy geraniums ( there is an evergreen one or two) ferns,hostas.

Also, iris foetidissima, grows well, very hardy, evergreen.

Polygonatum (Solomon’s Seal) is lovely & should be ok.

Oh sorry it’s not evergreen.

Butchers broom or Ruscus aculeatus is unusual. www.rhs.org.uk/Plants/220446/i-Ruscus-aculeatus-i-John-Redmond-sup-(PBR)-sup/Details
I’ve never seen red berries on one though.

Thanks to all. I think I will try male fern which I like the look of, and perhaps one butchers broom to see how it does.
I do like the look of the dead nettles but I fear the area is too shady for any sort of nettle.

BTW, iris foetidissima, I had a lot of these self seeding including in complete shade under the crab apple. I can vouch for their hardiness. I simply disliked the nightmarish blooms so much I had them all dug out.

Pachysandra terminal is?

Bergenia (elephants' ears)? Leaves go lovely shades of red and purple in the winter. Pink flowers in spring.

Sorry meant to post earlier and forgot.If it's ferns you're looking for I have found Bowdens Hosta and Fern nursery to be excellent to order from.Plenty of information on suitability and which are evergreen.And the slug resistant hostas really are .
