Campanula Rapunculoides vs C. punctata

Asked April 29, 2017, 12:37 PM EDT

Some years ago a neighbor gave me some C. Punctata. Because Creeping Bellflower is so invasive the two have mingled & I can no longer tell the difference between them at this time of year. I'm not even certain if I have Punctata any more, but what is certain is if I let Creeping go now it will take over. Can you tell from the pictures I've attached if there is a difference between these plants? I am sure that the first one is creeping bellflower. Are the others the same?? Thanks for any/all help!!

Your neighbor did you no favors. In some parts of the country, C. punctata is also considered invasive. And you know C. rapunculoides (creeping bellflower) is. You will have a hard time telling the plants apart , at least until they flower. So I'd try to get rid of all of it. Read here:
