Mary Mary- how does your Garden Grow?

[Maze]

If the noxious plant can be kept without it doing unacceptable harm to the rest of the garden, if not by smart designing than by a not too ridiculous amount of work..

Sure.  

[RedRoseSpiral]

Any plants like that I'm going to have I will keep nicely trimmed up so it won't get out of control. I've always wanted a brick house with one wall covered in ivy. I've always loved the effect. Really that would be the only noxious plant I would have and the only place I'd have it.

Would folks be willing to bud plants to prevent seeds from spreading?
