Does anyone know this tiny yellow plant?

[Antje Schulte]

Hi all,

My neighbour's dog has just killed my favourite weed (had to chase mice I guess... :-/ ), and I don't even know the plant's name. I'd love to replace it, I've always found it very interesting, but I don't know what it is. Does anyone know what this little plant is called?

's very tiny, maybe 5 cm tall, and has tiny yellow petals as you can see. Oh yes, and it used to live in Germany...

Thanks in advance,

Antje

Thanks Mike, you're right, I think it might be one of the Sisymbriums but can't get to the species somehow...

Cheers,
