Crocuses are poking through already. Crocus tommasinianus in shades of magenta, lilac and white are the first to show themselves in the garden and a pot of Crocus angustifolius is coming into flower on a window sill, a variety called 'Cloth of Gold' :

 The bright orange anther and pollen sacs dusted with pollen are very prominent when the petals of the Crocus unfold and open to the sun- though I don't think many bees will venture out in the damp chill of a day like today.
