This is not exactly a flower, I think it may be a vegetable of some sort. It stands about four feet tall and has white flowers all over, and pods that seem to get red lines on them as the mature.
Raphanus raphanistrum perhaps? http://cropandsoil.oregonstate.edu/weeds/Wild_raddish/rosette.jpg HTH Chris
I also think "radish" having seen a huge plant at UBC's botanical garden. A garden volunteer urged us to taste the young seedpods. An eye-opener!
Thanks. I had suspected it was a radish plant, but the pods were confusing. I researched based on the info you provided, and found that there are radishes grown for their pods! Had no idea! München Bier was the name that kept coming up in my search. Will have to give these a try.
