And what else is the garden doing in late April?

Pignut (Conopodium majus) is beginning to flower

Next door's ornamental cherry is in blossom and hanging over into our garden

Spears of Pyramidal Bugle (Ajuga pyramidalis) are shooting up

Ajuga pyramidalis from above

Liverwort and moss growing together on an old tile under one of the companionway steps.
I think the liverwort is Pellia epiphylla (dead common round here) and the moss is, I think, Common Feather-moss (Kindbergia praelonga/Eurynthium praelongum)

 Lady's Mantle catching raindrops

Here the gardener is attempting to be arty with violets.

She is not sure she has succeeded, but the colour is nice.

 Wood sorrel beginning to flower on the north-east facing front garden wall

Shoots of Solomon's Seal in front of a rotting trunk in the lane

The weight of ivy and winter gales brought the top half of the old trunk down

which benefited the roe deer as they could eat the youngest ivy leaves

Herb Bennet (Geum urbanum) leaves

Herb Robert (Geranium purpureum) leaves

and Hawthorn almost ready to flower

The weight of ivy also weighed down that hawthorn tree but it is still thriving

even bent right over to the ground

A mass of tree trunks and ivy trunks

And lastly, for now, the fallen wild cherry is still flowering away, though when the wind picks up we have cherry petal snow

Thus

You can see in that picture, if you enlarge it by clicking on it, just how much of our upper lawn is pignut.
