I have these plants growing a meter or so from my house:
I have no idea what they are, but I quite like them, so would prefer to keep them if practical. However, they have a tendency to spread easily (perhaps they're considered weeds?), and of particular concern is that they're coming up in between the sealed edge between house and footpath:
To be honest, I don't even understand how they're growing there, since there's no water and I would have thought there's no nutrients being the foundation of my home. Presumably, the high humidity is sufficient to allow these things to thrive.
If I try removing them by simply pulling them, the stem detaches from the base and they promptly grow back.
What should I do to deal with these suckers more permanently? I'd prefer to avoid any herbicides or harsh chemicals, since I don't want to expose my family or dog to anything toxic if I can help it. Any idea what I can do?
