Weed with a HUGE tap root!
I am seeing these things grow all over my yard. They like to grow in really fertile areas, like where my roses and vegetable garden is. They have very large leaves tapering off a single red thick stem. The stem is flexible and fleshy. They are a pain to pull out because they grow an enormous thick tap root, like a white carrot of some sort. These things grow extremely fast too. I'm wondering what these things are and where they come from.
