Not all plants are suitable for adjoining areas. Some flowers and shrubs, despite their attractive appearance, can be quite dangerous both for your site and for your neighbor's.

Experienced Garden on a Roll gardeners emphasized that some plants should be avoided. The Express has found out which green spaces can do more harm than good.

Pontic rhododendron

The Pontic rhododendron is a fairly popular garden plant due to its striking appearance. It is a branched evergreen shrub or, less commonly, a small tree reaching 5-8 m in height. The base of the leaf blade is rounded or wedge-shaped, the end is pointed. Rhododendron is best avoided because this invasive species can spread rapidly and smother native plants. The variety produces toxins that inhibit the growth of other plants.

Leyland cypress (cuprocyparis leylandii)

Leyland cypress is an evergreen tree that grows quickly. No, it is not toxic or poisonous, but it can cause disputes between neighbors due to its ability to quickly block light and views. Cypress needs to be pruned frequently to keep growth under control.

Himalayan balsam

Himalayan balsam is an invasive plant that can outcompete native green spaces for light, space, and nutrients. This species is very aggressive. In open areas, its rapid spread can lead to soil erosion and increased flood risk, as it dies in winter, leaving river banks open.

Yellow archangel

Yellow archangel is an attractive forest plant that can become invasive if planted in the adjacent territory. The plant spreads quickly through underground pathways and can choke out other plantings at an early stage. It is very difficult to remove this species from the garden.


Monbretia is a popular garden plant, but its rapid spread can lead to certain problems. Monbretia quickly forms dense clumps that are difficult to remove, thus outcompeting native plants and reducing biodiversity in your garden.

Common bamboo

Bamboo can add an exotic touch to your garden or be an unpretentious houseplant, but some species, such as common bamboo, can become invasive if left unchecked. Garden bamboo requires careful maintenance. Its aggressive root system can spread quickly and cause damage to other plantings.

Cherry laurel (prunus laurel)

The cherry laurel is an evergreen shrub that can quickly form a dense, impenetrable stand. Its overly active and dense growth makes it unsuitable for small gardens. The plant can also be toxic to humans and animals if ingested.
