Please help my identify this plant
I have this plant that I have tried to eradicate from my flower box. It reproduces by bulbs multiplying like crazy. I recently dug up al of the bulbs and left a few in the ground. The ones in the ground managed to push their way through a then breathable plastic and up through 4in of mulch. How do I stop them from growing or should I just start making money off selling them?
