It's wild how invasive creeping bellflower is. It's pretty purple flower, so people think that it's just another flower which is part of why it has staying power. The rest of it is the fact that each plant can generate 15,000 seeds, can spread through a root system under the soil, and can regenerate from fragments of the root. If you have it, you'll have to keep digging it up every year for some time.
