Elder added to the list - with some nice buds coming through in the early morning sunshine - just prior to the morning rain!
Daffodils are on their way (who knows what variety!), and so are Dandelions, while Ribwort Plantain leaf rosettes are popping up along the verges. There are also a couple of Rumex species (Dock/Sorrel) but I'm still ruminating on those. Poland may have to come off the shelf.
(edit: pulled some leaves out my collection box - Common Sorrel, Rumex acetosa)
