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 ....

As another poster has said, Linaria purpurea, Purple Toadflax
And...
Marsh Woundwort - very pretty and great for polinators, but spreads like wildfire, like all the Lamium family

Ditto Creeping Jenny
Ditto Acanthus mollis
Ditto Chinese Lantern
Ditto Red Valerian

The list goes on, but at least the garden is abuzz with bees, butterflies and other pollinators!

Fucking periwinkle!

Yes, vinca. Nightmare.

Grape hyacinths and valerian. Both capable of breaking concrete.

Oh, and bluebells. I bought them as English bluebell bulbs, only they turned out to be the Spanish ones and now I can't get rid of the bastards.

Mallow. It’s taken over a bit, and looks as it it’ll be a bugger to dig out now.
An amelanchier which the garden centre assured us would be perfect for a corner of our garden. I think they wanted to get rid of it and it’s done fuck all.

Bamboo.
Spreading 😮😩

I absolutely love purple toadflax.

<misses point of thread entirely>

Hideous stuff. It was in my garden when I bought the house, I got someone in to dig it out and for several years I didn't have too much of a problem with it.

Unfortunately, my neighbours allowed it to grow their side, they do not do anything in the garden at all, so it's now threatening the base of the wall of their extension which I have pointed out.

It's also now growing back my side too and coming up in the lawn.

Bastard stuff!😡

Alstromeria .... spreads rampant-like underground with horrid tubers & then sprouts garish red or yellow- not pretty, muted - coloured flowers. Hate it with a passion but its everywhere!
At least I didn't plant it, silly previous owner did as a "good filler".

Hops. Have a love how fast it grows but also hate how fast it grows and spreads. Pretty sure triffids were modelled on it

Montbretia. Japanese knotweed has nothing on this thing.

Dug it up two years ago and still get about 50 new shoots a week.

These are my bloody nemesis. Honestly rue the day.

See also golden hop and passionflower. Utter utter thugs (actually I didn't plant them, I inherited them but sometimes I'm tempted to go round to their new house and have a word!);

My patio (hah!) buddleia grows 6ft tall every year despite being
chopped back in spring. I like it but not where I planted it. Still, it's got nothing on the self seeded monster between us and next door, also gets chopped every year but currently about 16ft high. Covered in butterflies though.
Pulmonaria (lungwort). Gorgeous in spring, covered in bees. But it spreads like crazy, and gets mouldy underneath where you can't really see, and it's covered in hairs which really irritate my skin. So glad I begged a cutting of that one!
Vinca. Yep.

Currently regretting my 7ft plus teasels.
Yes the bees loved them, but the flowers have lasted all of 5 minutes and now they’ve shed their seeds all over. They are also so big, and I have so many of them (seeded from ONE 4ft plant last year) that they won’t fit in the green wast bin I pay the council for. The buggers are also really, really prickly. I’m going to get shredded ripping them up this weekend.

Forget-me-nots 😔My Granny had some in her garden so when she passed away, I reverently planted a small patch of seeds in her memory. Except I didn’t realise she retired at 55 and spent her days tending to the garden so kept her forget me nots under strict control. Mine on the other hand are effing EVERYWHERE and huuuge.

Minipie - I mildly regret planting hydrangea Floppy Annabelle, not least because she put me to the expense of buying a plant support. I’ve just noticed that one of the stems has broken under the weight of the flower head. Ho hum.

Yep, we have our Annabelle supported by wires (they’re against a fence) but they just flop over the wire. Maybe I need to look at other supports, though sounds like they may not help much...

ThreeKnees I also have a rather sulky amelanchier. It flowers beautifully for a week across May half term, when we are always away. Then looks unhappy the rest of the year. Sigh.

I also regret choosing plumbago to cover an ugly bare wall. Did beautifully until the frosts last winter when it up and died, so I’m starting again with the wall coverage (with a sollya heterophylla which is also only semi hardy…. I don’t learn).

I now slightly want to plant pendulous sedge purely because the name amuses me. Don’t worry I won’t!

Sloe bushes 😱

OMG sloe bushes, the runners grow out from the main plant, you can't just pull them up, they want my whole garden!

We've reluctantly come to the decision to kill the bastard

In the past I have regretted Virginia creeper and honeysuckle.

I bought a peony-type support for Annabelle but was late to spot that she needed it, so she’s rather crammed in. Obviously it hasn’t been enough to stop the stem breaking!

My amelanchier is very tall and spindly. I’m wondering whether pruning would encourage it to bulk up.

Vinca, I second that, smothers everything.
also what was supposed to be a pink dwarf pampas, only five feet tall. It's not pink, and it's huge, despite cutting it back every year. It would need a team of navvies to get it out.

In the garden when we moved in vinca, orange crocosmia and three cornered leek, still in the garden...the bastards. Mind you next year they might be fighting it out with the grape hyacinth which was a gift that I carelessly allowed to seed.

I didn’t plant them, but fuchsias. Don’t like them. Pulled three of them out of my garden by the roots three years ago, or so I thought. All three have reappeared this year.

In my old house we got overwhelmed by self seeding poppies.

I have a bay laurel which felt like it appeared overnight and is now ten feet tall 😕

Penstemons... beautiful peachy colour, but not when it takes over the entire length of the border... hacked back/dug out every year, but the bugger spread underground.
