Gardeners warned of 7 ‘troublesome’ plants to never grow that’ll cause neighbour disputes
Garden plants can add fantastic colour and interest to your outdoor space. However, there are those that should be avoided, warn gardening experts.
Gardeners may be eager to fill their outdoor space with a diverse array of plants this new year.
However, not all plants are suitable for gardens, and some can even "cause more harm than good”, warned the expert at Garden on a Roll.
They have shared several plants you should “never grow in your UK garden”, either because they're “invasive, harmful to native species, or difficult to manage”.
1. Rhododendron ponticum
Although absolutely stunning, rhododendron ponticum is an invasive species that can “spread rapidly and smother native plants”.
This plant also produces toxins that inhibit the growth of other plants, making it “particularly troublesome” for UK gardens and woodlands.
2. Leyland cypress (x cuprocyparis leylandii)
Leyland cypress is a fast-growing evergreen tree that can “cause disputes between neighbours” due to its ability to quickly block light and views.
It requires frequent pruning to keep it in check, making it a high-maintenance option for your garden.
3. Himalayan balsam
Himalayan balsam is an invasive plant with an “aggressive growth habit”, capable of outcompeting native plants for light, space, and nutrients.
Its rapid spread can lead to soil erosion and increased flood risks, as it dies back in winter, leaving riverbanks exposed.

4. Yellow archangel
Yellow archangel is an attractive woodland plant, but it can become “invasive in your garden”.
The plant spreads quickly through underground runners and can smother other plants, making it difficult to control once established.
5. Montbretia (crocosmia x crocosmiiflora)
Montbretia is a popular garden plant, but its rapid spread can become “problematic”.
This plant quickly forms dense clumps that can be difficult to remove, outcompeting native plants and reducing biodiversity in your garden.
6. Common bamboo (phyllostachys aurea)
While bamboo can add an exotic touch to your garden, some species, like the common bamboo, can become invasive if not carefully managed.
Its aggressive root system can spread rapidly and “cause damage” to structures and other plants in your garden.
7. Cherry laurel (prunus laurocerasus)
Cherry Laurel is a fast-growing evergreen shrub that can quickly form dense, impenetrable growth, making it “unsuitable for small gardens”.
It can also be toxic to humans and animals if ingested, so consider alternatives if you have children or pets.
