This is a birdseed alien from Europe which appears from time to time. At this site there were plenty of young plants suggesting that it is well established. I visited it twice to try to find more mature flowers but it must flower in late August by which time I was in Australia.

There are a few records from England and one or two from Wales and Scotland and none from Ireland for this alien.
