Alive with bees!

(We both got our flu jabs at the chemist today, free this year for over 50s, yay!) 
Rob drew my attention to this plant today, he could hear the buzzing as he walked down the path. It is behind several shrubs and so I could hardly get to it but whatever it is the bees and butterflies and flies are just in heaven! I am pleased as there is not that much in the garden at the moment for them. 
I have more allium bulbs to plant this year but I think I will do them in a couple of weeks. Feels a bit too mild at the moment.
