The Heritage Loam Soils 80% Grass Mix Wildflower Seed is expertly blended for sites with fertile, loamy soils – a common soil type found across much of the UK. This wildflower seed mix contains 80% low maintenance grasses and 20% native wildflowers, offering a balanced and naturalistic wildflower meadow that is both visually striking and environmentally beneficial.
This seed mix is perfect for parks, gardens, open spaces, road verges, estate grounds, field margins, and restoration sites, where loamy soils provide a good base for diverse floral growth. Species in the mix, such as Ragged Robin, Common Dandelion, White Campion, and Yellow Rattle, establish well in nutrient-rich soils and help attract bees, butterflies, and birds to the area. Grass species offer durability, structure, and soil stability while allowing wildflowers to thrive.
All wildflower seed mixes are subject to change, dependent on the time of year, harvest, and may include more species than listed above.
