Have you ever planted something that has gone wrong? Much of gardening is learned by trial and error, but new research uncovered the top plants people regret ever putting in their gardens.
According to the Hardy Plant Society (HPS), the UK's largest Specialist Plant Society, acanthus is the 'problem plant' gardeners regret planting the most, followed by Lysimachia and Japanese Anemone.
Commonly known as bear's breeches, clump-forming acanthus was described as 'invasive', with many saying it's difficult to remove. One member of the plant society described acanthus as 'worse than bindweed or ground elder'.
Meanwhile, Lysimachia is also considered a vigorous plant that can also become invasive if left unchecked.
The research found Japanese anemones to be 'a thug on good loam' as people said it can quickly swamp other border plants and spread at an uncontrollable rate.
"I'm in complete agreement with the first choice of garden regrets, however, having spent years ruing the day I planted Acanthus mollis in my garden as a novice gardener," says Steve Bustin, Chair of The Hardy Plant Society.
What to Read Next
"Experienced gardeners know the plants to avoid but when you see any of our 'most regretted' plants on sale in a garden centre the label gives no hint of the misery that plants might come to inflict over the coming years.
"It would be good to see some of these plants carry a 'health warning' that in some gardens (not all) they might become a problem."
Top 8 plants that gardeners regret buying:
- Acanthus
- Lysimachia
- Japanese Anemone
- Hardy Geranium
- Euphorbia
- Yellow flag iris
- Mint
- Russian vine
While these plants are not dangerous, they can quickly get out of hand in a garden due to a very vigorous growth rate or the ability to spread easily.
Also on the list is flag iris, a pretty yellow flower that loves a wet spot in full sun or partial shade. It might be great for pollinators but can quickly take over, creating extensive colonies up to 1.5 metres in height. If you only have a small pond, avoid growing this and opt for marsh marigolds, water lilies or pickerel rush – all of which will keep bees, butterflies and hoverflies happy.
Likewise mint – delicious added to teas, salads, soups and sauces, this versatile herb is also incredibly vigorous (spreading via underground rhizomes), so be sure to plant in a pot rather than directly in the ground.
Also, Russian vine – this woody deciduous plant goes by the moniker 'mile-a-minute' vine thanks to its incredibly fast growth: up to four metres per year. According to the RHS, diligent summer pruning is paramount to keep this climber under control.
If you already have invasive plants in your garden, remove seed heads and pods regularly to stop them from spreading. Contact the experts if you are concerned.
