Hi, I've been reading all the horror stories of weedy Oxalis. When I tire of this plant, I put it in a plastic bag,,, pot, soil, and all, and put it in the garbage. An even scarier plant for me is Ranunculus ficaria, and it's cultivars. If you don't have any of these garden treasures, please specify how many dump trucks of this plant I should have delivered your way, and I could happily fill your order. Think spring,,,, but BE Careful out there with your plants. Rick K
