Purple flowers on the boulevards?

My mum came and visited last year and loved all of the purple flowers on the boulevards -- ie down the center of 9 de Julio and pretty much in any of the public parks, the tall stalks with purple flowers. She wants to see if she can find them back home to put on her terrace -- does anyone have any idea what they are called? I haven't a clue. I don't know if they are native to here or if you can easily find them in North America, but they seem to grow like weeds so would be easy to have!

I've got them in my garden in Los Angeles and they are quite easy to find in LA and grow easily (with a fair amount of benign neglect on my part).

LA is in zone 10. They will grow well there. You can't grow them outside in New England or Memphis, etc! :)

In Belgium we put them in pots on our terraces, and take them inside in winter : they die of frost... It is not easy to keep them if you have frost.
