Answer: Once established, morning glories usually spread invasively. In some states, certain varieties are considered noxious weeds and it is unlawful to plant them as they will choke out other native species. Since you "found" these plants it's difficult to say what they will do. I'd suggest trying them somewhere where you can more easily eradicate them if they do become a problem. I wouldn't recommend planting them amongst other plants, as overcrowding reduces air circulation, which creates a perfect condition for certain disease problems to take hold. I hope this info helps!
