Help identifying plant
I can't upload a photo but have a very odd plant growing through my gravel path and would appreciate any help in identifying it. It seems to grow from small brown bulbs and has a white stem turning dark pink/indigo at the end. The flowers are four leaves which are mid/light green at the end and dark pink/red near the stem. When I dig it up there are loads of white stems that fragment very easily. I have tried to be thorough digging it up but it still comes back. Thanks for any help.
