A neighbouring flower

I caught the bus to work today because I needed to catch up with reading for a meeting which was first thing. How sad is that? No exercise because I was behind with work! Anyway the advantage of taking the bus is walking to the bus stop (I cycle or run, but rarely walk anywhere) and noticing things I wouldn't see on a bike. Like this flower in our neighbour's garden. Does anyone know its name?

I had to bribe the hens to come out of their run with corn this afternoon. They don't like snow ;o)
