what is this NOXIOUS weed?

It pops up every year in different planters (outdoor.) Grows seemingly overnight. Has a very strong single stem with two or 3 bi-lateral, long, jagged leaves on top, and a NUT-LIKE ROOT. Most importantly, it seems to poison other plants in the planter. Once I pull it out, the other plants look happy almost immediately. What is this thing?
