Create stunning wildflower meadows on loamy soils with our Heritage Loam Soils 100% Wildflower Seed Mix, carefully curated as part of the John Chambers Wildflower Seed Heritage Range. Designed to support biodiversity, enhance visual appeal, and provide vital pollinator habitats, this 100% native wildflower seed mix is ideal for enriching medium fertility loam soils typically found across much of the UK countryside and urban green spaces.
This diverse and vibrant wildflower mix contains only UK-native wildflower species, with no grass seed included, making it the perfect choice for projects where wildflowers take centre stage. The mix supports sustainable planting schemes, contributes to net gain biodiversity targets, and enhances natural ecosystems in areas such as parks, road verges, meadows, gardens, open green spaces, hedgerows, riverbanks, and farmland.
Featuring classic native wildflowers like Ragged Robin, Common Sorrel, Common Dandelion, White Campion, Yellow Rattle, and Hoary Plantain, this mix is designed to thrive in loamy conditions and bloom throughout spring and summer. While these species are key representatives, the full mix may contain up to 20–30 additional wildflower species—selected based on seasonal availability and UK provenance—to provide extended flowering periods, colour variation, and broader wildlife value.
