Stumpery

From this

to this

Now filled with really good leafy top soil. I cut back some of the overhanging branches to let in more light and rain. We cannot do anything with the Beech on the right as it has a TPO on it.
Now I need to plant it up. Suggestions?

 

It looks like a shaded area Palustris? I think woodland plants and bulbs would be a start. I have five mature pines in a group and I've started planting in and around the area with natural Primroses and Snowdrops. I've also added some Crocus and Chionodoxa and will gradually add other plants like Anemones and Hellebores.

 

The whole of the rest of that area is going to be filled with Snowdrops, primroses, cyclamen, Anemone nemorosa, A. blanda and such like so I was looking for something slightly different for the raised bit in the stumps.
Have already put in some Epimedium, Polygonatum, Pulmonaria, Cornus canadnesis and one tiny fern from elsewhere in the garden.
