What is it?

Is this some sort of clover? It came up in a patch where I sprinkled some butterfly and bee flower seeds but doesn't seem to be anything listed on the box.
Another lovely day, less breeze but what there was was coming from the east so quite fresh.
Made bread and ice cream (and ate some of each), gardened, pottered, sewed and the day went by. 
The ice cream had redcurrants and yellow rasps in it. Usually the yellow ones are later but they've started earlier. I think I need new currant bushes, both red and black had a poor harvest but they are quite old, esp the red ones.
