The only one that I've planted in this house and regretted is Acanthus Mollis. No matter how much I dig up there is always more the following year. I planted Houttuynia Cordata at my last house, it was a thug and smelt awful. Just couldn't get rid of it. I was so pleased to leave it behind.

Nicandra aka The Apple of Peru. Some seeds from a "friend" produced lovely plants. That seeded themselves. That continued to pop up for years and years. At least the seedlings were easy to spot and deal with!
Not that I waste a lot of time on controlling it but the one plant I can think of that I would reconsider introducing to the garden has been Chinese bramble (Rubus tricolor). I was hoping to taste what its fruit is like but I have yet to find one and just read there that it only occasionally produces fruit. There is very little chance of digging it out where it is growing in fairly stony ground and its stems look fairly unsightly in the way they grow up the nearby shrubs. I cut it back occasionally and have even added some vinca to grow next to it and help limit its efforts to spread further. I did plant it somewhere previously dominated by standard type brambles as I read it was a vigorous competitor but I think I actually prefer to see normal wild brambles with their nicer flowers and fruit.

We grow houttuynia cordata as a herb/ salad. The whole plant is edible. The smell of it seems to affect people differently, some say it’s horrible so it’s also called fish mint, I think it smells good. It can definitely spread though even between slabs.
re Acanthus mollis - my neighbour has it ( one plant) -- left over i assume from bit of root from prior occupants before they decided to plant a yew hedge in same space. We're basically London terrace with courtyard type gardens separated by very low walls, so unsurprisingly the acanthus shoots reach sideways into my courtyard to get some light vs growing up through the yew. I was under impression it is impossible to get rid off if you decide you don't want it where you planted it, but doesn't "spread" as such ( at least that's been my experience , over last 3 or 4 years of this specimen, but maybe the yew on top is inhibiting its spreading tendency ).

I've spent the last 5 years trying to dig it out as it doesn't flower much at all but it comes back with a vengeance in several beds.
Now I've planted Rozanne in the beds that didn't have Johnson's Blue. Sucker or what!
