Government advises homeowners to select flood-resistant plants such as river birch and dogwood to bolster gardens against increasing flood risks, blending ecological strategies with aesthetic appeal amidst rising climate threats.
Homeowners in the UK are being encouraged to cultivate gardens specifically designed to withstand and recover from the increasing threat of flooding brought on by climate change. The Department for Environment, Food and Rural Affairs (Defra) has identified five key types of plants—including trees, shrubs, grasses, and flowers—that can enhance a garden’s resilience to heavy rainfall and waterlogging.
Defra highlights species such as the river birch (Betula nigra), valued for its rapid growth and shallow root system that helps stabilise the soil and absorb water efficiently. The dogwood shrub (Cornus sericea), with its characteristic red stems and fibrous roots, is also recommended for its ability to reduce soil erosion. Other plants on the list include mace sedge (Carex grayi), which slows water flow with its dense tufts, yellow flag iris (Iris pseudacorus), known for stabilising wet soils and bright blooms, and red bistort (Bistorta amplexicaulis), a pollinator-friendly groundcover suited to damp areas.
These flood-resilient plants work as natural “sponges,” absorbing excess water through roots and leaves, thereby slowing runoff and facilitating better soil drainage. Defra stresses that planting such species should complement other flood preparations, including checking local flood risks, signing up for warnings, and devising flood response plans. Flood Minister Emma Hardy underlined the practical benefits of gardening for flood resilience, urging residents to “dust off your spades” and prepare their gardens to better withstand winter downpours.
This push comes amid warnings from the Climate Change Committee that the UK is ill-prepared for the escalating frequency and severity of extreme weather events exacerbated by global warming. Gardens represent a vital frontline in mitigating flood damage as urban areas become increasingly vulnerable.
Additional insights from the Royal Horticultural Society, presented at the 2024 Chelsea Flower Show, further expand on plant options that combine aesthetic appeal with flood resilience. Their showcase featured quince trees, with robust root systems ideal for wet soils; resilient pollarded willows; adaptable Ranunculaceae species suited for damp conditions; and ground-covering annuals and biennials that support pollinators while quickly stabilising soil. These choices exemplify how garden design can thoughtfully balance beauty and function in flood-prone settings.
The London Fire Brigade also advocates for particular trees and shrubs in flood management strategies, citing species such as yew, cotoneaster, and western red cedar for their dense canopies, which store rainfall. Certain flowering shrubs like forsythia, hawthorn, and privet contribute by evaporating significant amounts of water, reducing runoff and the risk of flooding.
Private sector actors, including insurer Aviva, echo this focus on flood-resilient gardening. Their British Rainforest Garden concept highlights biodiversity alongside flood prevention, featuring native and shade-tolerant species like silver birch, maidenhair spleenwort fern, and cow parsley, which thrive in wet or shaded areas while supporting wildlife and ecosystem health.
Flood Re, an organisation specialising in flood risk awareness, lists further valuable plants such as water mints, astilbe, and male fern. These species not only manage moisture but also provide habitats for pollinators and wildlife, enhancing garden ecology in flood-affected zones.
Moreover, experts emphasise planting dense shrubs like hawthorn and holly as natural windbreaks, deep-rooted perennials to prevent soil erosion, and low-growing groundcovers like creeping thyme that maintain soil structure and enable better water drainage. Proper placement and combination of these plants create gardens that offer year-round protection against flooding and storm damage.
The Flood Resilient Garden project by Flood Re demonstrates practical applications of these principles, featuring diverse plant zones from sunny banks to boggy areas, integrating species such as hydrangeas, salvia, lilies, and various grasses. This approach shows how ecological landscaping can both reduce flood risks and deliver aesthetic value.
As flooding risks rise in tandem with climate change, these multiple expert-backed strategies underline the role of gardening as a cost-effective, environmentally beneficial way for homeowners to mitigate flood damage and support broader resilience efforts.

The draft above was created using the information available at the time the story first
emerged. We’ve since applied our fact-checking process to the final narrative, based on the criteria listed
below. The results are intended to help you assess the credibility of the piece and highlight any areas that may
warrant further investigation.
Freshness check
Score:
8
Notes:
The narrative is recent, published on 17 October 2025. The Department for Environment, Food and Rural Affairs (Defra) has highlighted five key plant types to enhance garden resilience against flooding. This information aligns with previous reports from the Royal Horticultural Society (RHS) and Flood Re, which have discussed similar plant recommendations for flood resilience. However, the current report provides updated context and additional details, suggesting a moderate freshness score. No evidence of recycled content or significant discrepancies was found.
Quotes check
Score:
7
Notes:
The report includes a quote from Floods Minister Emma Hardy urging residents to ‘dust off your spades’ and prepare their gardens for winter downpours. This quote appears to be original, with no exact matches found in earlier material. However, similar sentiments have been expressed by Hardy in previous statements regarding flood preparedness. The wording varies slightly, indicating potential reuse of content.
Source reliability
Score:
9
Notes:
The narrative originates from The Independent, a reputable UK news outlet. The information is attributed to Defra, a government department, and includes direct quotes from Floods Minister Emma Hardy, enhancing credibility. No unverifiable entities or fabricated information were identified.
Plausability check
Score:
8
Notes:
The claims about specific plant species enhancing garden resilience against flooding are plausible and supported by previous reports from the RHS and Flood Re. The inclusion of a direct quote from Floods Minister Emma Hardy adds credibility. The narrative lacks specific factual anchors such as exact dates for the plant recommendations, which slightly reduces the score.
Overall assessment
Verdict (FAIL, OPEN, PASS): PASS
Confidence (LOW, MEDIUM, HIGH): HIGH
Summary:
The narrative is recent and originates from a reputable source, with plausible claims supported by previous reports. The inclusion of a direct quote from Floods Minister Emma Hardy adds credibility. While there is some evidence of content reuse, the overall assessment is positive.
