SuDS that Work: The Benefits of Using Pictorial Meadows Turf in Flood Resilience Schemes

In this blog post, we explore the ecological, practical and social benefits of Pictorial Meadows SuDS Turf and its role in creating more sustainable, resilient landscapes.

Sustainable Urban Drainage Systems (SuDS) are critical tools for managing stormwater, mitigating flooding and enhancing water quality. But when wildflower meadows are incorporated into SuDS schemes, the benefits extend far beyond functionality. Pictorial Meadows SuDS Turf provides a range of ecosystem services, transforming flood resilience schemes into high-value, multi-functional landscapes that blend ecological, practical and social benefits.

With over twenty years of experience in flood resilience landscapes, Pictorial Meadows has developed a range of SuDS Turf solutions that have been rigorously tested across bioswales, retention ponds, basins and rain gardens. These wildflower mixes have been successfully implemented in Green Flag award-winning urban parks and major UK SuDS projects, including the Sheffield Grey to Green Scheme and the Mansfield Flood Resilience Scheme. Used by civil engineers, landscape architects, councils, housing developers and water companies, Pictorial Meadows SuDS Turf not only supports drainage system functionality, but also delivers significant environmental and cost-saving benefits.

Instant Soil Stabilisation

Erosion control is a vital component of any SuDS scheme, especially when they are operational and receiving water from the outset. Pictorial Meadows SuDS Turf arrives as a pre-grown mat with 150 plants per square metre, with full root systems intact to instantly stabilise soil.

Anchoring Root Systems: Pictorial Meadows SuDS Turf is formulated with long-lived species with a range of root systems, such as the deep taproots of greater knapweed (Centaurea scabiosa), the extensive fibrous roots of purple loosestrife (Lythrum salicaria) or the dense spreading surface roots of yarrow (Achillea millefolium). Together, diverse wildflower species bind soil particles, preventing erosion and reducing sediment loss during heavy rainfall.

Organic Matter: The addition of leaf litter and root exudate supports soil fungal webs, improves soil structure and glues minerals together, while supporting soil resilience and stability even in areas exposed to high water flow and cycles of wetting and drying.

Reduced Runoff: Enhanced Water Infiltration and Percolation

One of the key challenges in urban areas is ensuring effective water infiltration to reduce surface runoff and flood risks. Pictorial Meadows SuDS Turf helps in a range of ways.

Diverse Root Systems: With around thirty perennial wildflower species, the natural seasonal cycles of root growth and decay in Pictorial Meadows SuDS Turf creates natural channels for water movement. This enhances soil permeability and ensures effective infiltration, even in compacted or degraded soils.

Leaf Litter: As wildflowers grow, they shed their lower leaves. As this leaf litter decomposes, it enriches the soil with organic matter, boosting its ability to let water through. This is especially important in dry periods, as it prevents hydrophobic conditions, allowing water to percolate effectively and reducing flood risks.

Reduced Soil Compaction: Unlike heavily trafficked grass lawns, wildflower meadows naturally reduce foot traffic, keeping the soil loose and promoting water absorption.

Protecting Water Quality

Stormwater runoff often carries pollutants like excess nutrients, sediments and contaminants into water bodies. Wildflower meadows created using Pictorial Meadows SuDS Turf provide natural water treatment within a flood resilience scheme.

Nutrient Uptake: Wildflowers absorb nutrients and heavy metals, reducing the risk of eutrophication and heavy metal accumulation in nearby water bodies. By cutting, removing and composting the meadow arisings, these nutrients are sustainably managed and turned into a valuable compost and used as a soil improver.

Sediment Trapping: Pictorial Meadows SuDS Turf uses a range of tried-and-tested long-lived perennial wildflowers that are adapted to growing and stabilising highly dynamic environments, making them perfect for use in flood resilience schemes. The dense network of stems, roots and leaf litter traps sediments and prevents them from entering waterways. Seedlings and rhizomes colonise sediment as it is deposited, helping prevent sediment mobilisation, preserving water quality and protecting downstream ecosystems.

Microbial Activity: Wildflower meadows support diverse soil microbial communities that break down organic pollutants, further purifying the water as it infiltrates the soil.

Reduced Maintenance

Silt Capture and Protection of Infrastructure: Sediment accumulation in drainage systems can impair their functionality. Wildflower meadows can capture silt and help protect the functionality of critical infrastructure such as drainage areas, orifices, overflows, pipes and permeable membranes.

Access for De-Silting: When sediment builds up, it can be easily removed once the wildflower meadow has been cut down, allowing full access to inspect and de-silt the site.

One Cut Per Year: Pictorial Meadows SuDS Turf provides a low-maintenance alternative to mown grass or more formal amenity planting, while proving very popular with residents and local businesses. Cutting operations are reduced to just one visit per year.

The Bigger Picture: Biodiversity, Economy and Wellbeing

Often at little to no extra cost, SuDS schemes carry an opportunity to deliver huge benefits beyond stormwater management. Large areas of amenity grass can be transformed into beautiful, engaging and biodiverse landscapes that deliver a myriad of benefits.

Wildlife: Diverse wildflower species in Pictorial Meadows SuDS Turf provide a variety of food sources (nectar, pollen, seeds) and shelter for a wide range of insects, birds and small mammals. Different plant structures create varied microhabitats, supporting a wider range of species. Carefully designed mixes for extra-long season flowering please both pollinators and people.

Boosting Local Economies: Beautiful wildflower meadows help create attractive and welcoming places where people want to spend time and money. Liveable urban places draw businesses and developers to invest in the area.

Health and Wellbeing: Beautiful wildflower meadows with seasonally-changing flowering displays encourage people to spend more time outdoors, foster social connections and feel saver in their neighbourhood.
