Very possibly... That might explain why the only recognizable leaves in the bin that its plant grows in are columbine leaves....

Darn. I was hoping it was some type of native phlox. This stuff is ALL over this wooded area. There are also white ones that look similar. Is there a white version?

And for removal of invasives (which this isn’t), I use large adjustable pliers to pull ones that are smaller. The looser the soil, the larger the plant you can pull. For large ones there a few choices: - Get a weed wrench or similar tool to pull midsized plants. https://www.theuprooter.com/tool-features/weed-wrench-alternative/ - Cut to ground level and then revisit each plant about every other week for a couple of seasons to remove all new sprouts so the roots use up all stored energy. This takes both consistency and persistence because if leaves get a chance to form the plant will start making and storing energy again. - Cut to ground level and then paint the cut with a short lived brush strength herbicide. I use this option along with the first because I live on 200 acres and it is my only hope of decreasing my invasives. I like it as the lesser of two evils because it is very targeted to individual plants, and it uses the least possible amount. I do recheck certain invasives even after this treatment once because sometimes buckthorn repsprouts, but IME recutting will kill it.
