Anyone know what this is? It comes up every year and makes a flower that looks like a sunflower. Sunflowers are annuals though and this comes back in the exact same spot every year. It gets roughly 6-8ft tall and then flowers. It doesn't seem to spread either.
Looks like a variety of helianthus tuberosus to me. Sunchokes. They will grow back from any little bit of root left in the soil.
If you're lucky, they are a variety whose roots get thicker. Mine only get as big as my little finger most times.
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
