SIGNS OF SPRING and REMNANTS OF SUMMER

Cow Parsley is already spreading  its ferny leaves although it won't produce its flowers until May

The first tree to leaf up is elder and it's started already in sheltered corners.  In the photo below you can just see a couple of pale leaves on the left.  Not the dark green ivy leaves on the wall.  

The bark of a maturing elder bush or tree has these joints on it that look a bit like skeletal arthritic knees.

Daisy means 'the day's eye' because not only do the flowers follow the sun's position in the sky but they close up at night, waiting for the morrow.

In contrast the leaves of wall pennywort or navelwort are evergreen.  The round penny-shaped leaves are unique in having the stalk in the middle, which is why there is a central dimple like a navel.

The dead flower stalks are a rich wine red, though they are greenish-white when they flower in summer.  The plant likes damp walls and steep banks.
