I have tons of that purple deadnettle, and mustard, I know those trees of heaven when I used to live in akron they grew everywhere out the cracks of cement walls, out of cracks in the sidewalks, out the cracks of steps brick and cement, they stinck too, but I always thought their flowers and seeds were pretty on them, these things even grew out the side of basement walls under the houses, amazing where they will grow, tough crittors.
