PLEASE! Help me get rid of Oenothera 'rosea'
High Country Gardens said that it "spreads rapidly on shallow roots" but didn't say it would overrun anything in its path! I hate this plant and want to be rid of this, my personal thug. I've dug and pulled and am afraid that any root or piece will again produce and "spread rapidly". Has anyone else had the ill-fortune to have to deal with this? I don't want to, but will I be forced to use chemicals? If so, I don't want to waste time digging and pulling anymore. Your thoughts and experience are requested! Thanks, Connie
