The Heritage Wet & Damp Soils 100% Wildflower Mix is carefully curated for wetter ground conditions such as stream edges, pond margins, marshy fields, floodplains, and poorly draining areas. This native wildflower blend is ideal for increasing biodiversity, colour, and habitat value in moisture-retaining soils.
This 100% wildflower seed mix includes UK-native species that naturally thrive in damp ground, ensuring long-term establishment and ecological benefit. It features attractive and wildlife-friendly species such as Purple Loosestrife, Gypsywort, Common Fleabane, Yellow Iris, Columbine, and Meadowsweet, with potential for additional complementary species depending on seasonal availability. The result is a rich, floral display that supports pollinators, amphibians, and aquatic edge ecosystems.
