Wildflower i.d. please
I'm not sure where this plant came from, it's in the yard in moved into. It's quite invasive also. It has white/beige tubers and they are fleshy. The plants stand about 3ft tall, some shorter, few taller. Here is a link to one pic of the flower head with leaves. The tall stalk does have leaves on it also, not many though. They leaf off the stalk in two's, not side by side, theya are staggered.
Thank you for any help!
