In the face of increasingly unpredictable weather patterns, the need to floodproof our gardens has never been more pressing. With surface water flooding emerging as one of the fastest-growing flood risks in the UK, it's time to rethink our garden designs. The 2026 RHS Chelsea Flower Show, featuring Flood Re's 'Contain the Rain Garden', highlights the importance of permeable surfaces, water storage features, and flood-resistant planting. Among the stars of this year's show are three plants that not only help prevent flooding but also add beauty and texture to your garden: Astilbes, Ferns, and Irises. These plants are not just flood-fighters; they are also shade-loving perennials that thrive in gloomier spots, making them ideal for a wide range of gardens. But what makes these plants so effective in flood prevention? Let's dive into the science and explore the broader implications of these natural solutions.
