Plant ID request please
The plant pictured centrally with the purple flower is the one I would like an ID for please. (there is another smaller one growing in the top right of the picture also)
Sorry about the poor photograph, I am hoping somebody will know what it is from this picture if not I can post some more when it is light outside! Photographed during the summer months, July possibly after most of the purple flowers were gone. I think this plant self seeded into my garden this year, or at least I don't remember it the previous couple of years. Only posted now as I have just recently become a member of the forum.
I do like the plant, but it has put down a LOT of seed, should I expect a lot more of these next year?
