I have this plant that started growing in a large whiskey barrel next to a golden plum tree I planted. Can anyone give me an idea as to what kind of plant it is? Any help would be very much appreciated. I would like to know if it's just a weed or what. It has about 7 or 8 smooth round shots coming up. They are pink /red in color. It's leaves are large. Almost as large as my hand. The leaves grow alternatively to one another.
