Eradication of "stinking iris"
What should I use and what method? They are popping up all over my backyard. I didn't realize they were so invasive, They are the greenish yellow flower with bright red/orange seeds in the pod. Thank you.

The best method is to pull the plant and don't let it go to seed. I suspect it is propagating through seed and rhizomes. I'd never heard of this plant but I found this wikipedia article https://en.wikipedia.org/wiki/Iris_foetidissima
