What Are the Most Invasive Bamboo Species in the UK?

Bamboo is not a single plant with a single behaviour. Roughly 1,400 species exist worldwide, and the ones sold for UK garden screening fall into two very different groups. The species that cause the overwhelming majority of removal work in South Wales and across the UK are running (monopodial) types, and a handful of them account for most cases.

What "Invasive" Means for Bamboo

In everyday use, "invasive bamboo" means a species whose underground rhizomes travel well beyond where it was planted, colonising lawns, borders, hard surfaces and neighbouring gardens. That is a horticultural and civil-nuisance description, not a statutory one — bamboo is not listed on Schedule 9 of the Wildlife and Countryside Act 1981, and it is not covered by the Invasive Alien Species Order. How far any individual plant actually spreads depends on the species, the age of the stand, soil type, moisture, light and whether anything physically restricts it.

The Species That Spread Most

Phyllostachys aurea (Golden Bamboo)

Widely sold for fast screening and one of the most common species behind UK removal jobs. Vigorous running rhizomes, canes typically 3–5m in gardens, and a strong tendency to send shoots up well away from the parent stand.

Phyllostachys nigra (Black Bamboo)

Popular for its dark mature canes. Often described in retail as well behaved, but it is a running species and established plants regularly move beyond their bed.

Phyllostachys bissetii and Phyllostachys aureosulcata

Both tolerate UK conditions extremely well, which is precisely why they spread. Frequently planted as hedging along boundaries, where the rhizomes end up on both sides of the fence.

Pseudosasa japonica (Arrow Bamboo)

Dense, shade-tolerant and very persistent. Forms thickets that are hard to clear by hand and readily colonises neglected ground.

Sasa palmata and Sasa veitchii

Low, broad-leaved and strongly running. Often planted as ground cover and then found spreading through borders and under fences. Widely regarded as among the most difficult ornamental bamboos to remove from a small garden.

Pleioblastus species

Several, including Pleioblastus simonii and variegated forms, run aggressively despite their modest height.

Generally Less Problematic Species

Fargesia species — such as Fargesia murielae and Fargesia nitida — and Bambusa and Chusquea are clumping bamboos. They expand slowly from a tight base and rarely cause boundary or structural disputes. A large mature clump can still be heavy work to dig out, but it does not colonise a garden the way a running species can. The RHS growing guide is a good reference point when choosing a replacement screening plant.

Why These Species Were Widely Planted

Running bamboos grow quickly, screen effectively, stay evergreen and were promoted heavily through the 2000s and 2010s as a low-maintenance alternative to fencing or leylandii. Labels often said "clump forming" or omitted the habit entirely, and problems commonly do not surface for three to five years — long after the plant looked like a success. That lag is why so many current owners inherited a running species they never chose.

Legal Status in the UK

There is no offence in simply having bamboo in your garden, and no statutory duty to remove it. However, if rhizomes from your plant encroach onto neighbouring land and cause damage or loss of amenity, that can give rise to a civil claim in private nuisance, and councils have discretionary Community Protection Notice powers under the Anti-social Behaviour, Crime and Policing Act 2014 where behaviour has an unreasonable detrimental effect. This is general information, not legal advice — take independent advice on your own circumstances. See our bamboo and boundary law explainer for more detail.

What to Do If You Have One

Start by confirming the habit rather than the exact species — our guide on how to tell if you have running bamboo sets out the checks. If it is a running type, map its extent, avoid disturbing the rhizomes and arrange a survey. Options then range from containment with a correctly installed vertical root barrier, through a professional herbicide programme over two to three growing seasons, to full excavation and disposal where a fast, thorough result is needed. Which is appropriate depends on the site, access and how far the network has already travelled.
