What do you regret planting in your garden?

[MyRabbit79]

Inspired by the current thread about the plants and weeds people are currently battling, what are the plants you've purposely sown or planted in your garden and come to regret?

For me, it's aquilegia and forget-me-nots.

I bought some aquilegia for our front garden when we moved here and it pops up everywhere, looks messy and I don't love the flowers

Forget-me-not - I sowed these from seed two years ago out the front. They're now everywhere including in the pots, gravel and back garden. Planning to pull most of it up after it's flowered this year.

Bloody snowberry . Its a thing of the devil. It spreads everywhere, total nightmare Proving troublesome when it gets into the wild, too

@userxx no, the monster one was green.
The red in the last house stayed small. The red one I planted in this house is waist height but quite wide, it’s a green one that had shot up!

My green one stayed small, the red one turned into a triffid. Bloody awful things once out of control.

Nasturiums - nightmare. Chuck their seeds everywhere and I can't get rid of them. Stupid bloody things.

Pyracantha. Fast growing and lethally spikey.
