What's the plant you regret putting in?

[BarrelOfOtters]

betony Great for wildlife it said, good for dry places....didn't mention it spreads like buggery and it a pain to dig out..not impossible but spreads under ground. Completely unsuited for my small front border....

There's also a rather lovely ceonothus that is rather too big for the spot by the greenhouse door and is making encroachments ....

Thank you both very much @Silvered and @Crikeyisthatthetime , I live in a humid subtropical climate zone and it looks like lavender might be the right answer! Geraniums unfortunately don't seem to be the best fit because of the weather here

Ah no. Sorry I assumed you were UK based! Good luck with the lavender

Bamboo should come with a warning . It’s a bloody disaster if not planted with care. My neighbours inherited bamboo from the previous owner. It looks for water so gravitates towards drains and water pipes. It came under their fence into our garden and started to lift up our patio and paving but did much more damage to their garden. In the end they had to hire a specialist company to dig the whole lot out which was very costly.

I regret that the previous owner of our house planted lemon balm and alpine strawberries down the side of the house. Both are absolute thugs.

So, so many. Chinese lanterns - pops up everywhere; Jerusalem sage, seeds everywhere; bloody red hot pokers, which my husband loves, flops everywhere.
Then there’s my beloved Ferdinand Pichard rose of which I buy a new one every time we move. In earlier gardens, it’s always been well behaved, in this garden it’s out for very, very thorny world domination. Sleeping Beauty would be jealous.

Are alpine strawberries the same as wild strawberries? I seem to have a put in quite a few of the plants mentioned here. 😬

Clematis old man's beard. It goes mad every year .

Same problem here with bamboo coming across from our neighbours’ side of the fence. We didn’t have too much trouble from it whilst it was growing 20 feet tall on their side but as soon as they decided to hack it down and supposedly dig it all out, it has gone mad, sending masses of new shoots up on our side. I’ve just had a whole new border planted up in that corner so I’m having to be really judicious with my use of SBK to try and contain the bugger 😡
It’s a bloody menace!
Also agree with PPs about Vinca. Horrible stuff. I planted some in our first garden when I was young and knew nothing about plants! I was still trying to dig it up, poison it, etc. to get rid of it up to 20 years later until we moved.

Japanese aenomes! Excuse spelling Cannot get rid of them in my geranium bed.

Next doors bloody (now our) bamboo... say no more.

I just googled Chinese lanterns and found:

Chinese lantern spreads via underground stems, in a similar way to mint, and can be invasive if grown in the garden.

😮

While it looks nice I think I will give it a miss.

I’ve just planted a load of Japanese anemone in the hope that it spreads like a bastard as my garden is very difficult.

Gotta laugh about all the comments about "thug-like" Vinca spreading everywhere. Here's mine, planted two years ago, and doing precisely nothing beyond lying in a stringy heap. I'm not sure I've seen a flower on it yet.

The idea was for it to cover over the lighting cable and soften the edge of the patio/French drain, but it hasn't even managed that. 🙄

Ooh @CointreauVersial don’t be fooled! It’s like a paddling duck - all looks calm on the surface but everything is going on underneath and out of sight 🤣 It’ll be spreading its tendrils under the soil and before you know it a whole new section of it will pop up several feet away! I was always getting my feet tangled up in shoots of it that lay like a spider web throughout my border. Shame it’s got such a pretty name ‘Periwinkle’ when it’s such a sneaky persistent bloomin’ pain in the arse!

Solidarity with all the bamboo owners. We inherited ours from the previous owners, and it’s bloody everywhere. I honestly have nightmares about it. Apparently it’s best to wait until autumn to get rid- first weekend in October, we’re hacking the lot down and.poisoning the stumps. Hateful, hateful stuff. I keep telling my husband we should hire a panda to deal with it, but he’s not really on board.

@Kazzyhoward buddleia does grow a lot between one prune and the next - I just deadhead it while flowering then when all the flowers have stopped flowering and they've started to go brown you can get the loppers and cut it back from 6-8ft high to 3-4ft - I think you'd be hard pressed too actually kill it. Butterflies and bees are all over ours. They are an easy plant to prune.

I have a mountain ash probably about 15ft high now. The structure is fine but it really hasn't lived up to expectations - it hasn't produced many brightly colored berries - I got it with the birds in mind. I like the dappled shade from it - I've pruned off she if the lower thin branches - it looks OK - I wish it would produce more berries though. No idea why it's so disappointing. Ideas? My wife wants to buy it down and get rid of it - I want to give it another chance. The past 3 years have been dismal.

I love our bamboo but it's a well behaved clumping variety, so easy to look after and keep in check. Garden centres shouldn't sell the running stuff without a warning, as it's so invasive.

lemon balm. I’m still pulling it out years after a friend gave my a cutting.

We have some, and I think it is lovely. Chalk soil, so happy it is spreading to fill the large border
