The Heritage Sandy Soils 100% Wildflower Mix is specially formulated for light, free-draining, nutrient-poor soils commonly found in coastal areas, heathlands, and sandy inland sites. This 100% wildflower mix contains a diverse selection of UK-native species that thrive in dry and fast-draining conditions, offering a visually rich and ecologically valuable habitat for bees, butterflies, and other pollinators.
Ideal for councils, landowners, landscapers, farmers, and professional gardeners, this mix adds vibrant colour and biodiversity to a wide range of settings, including open spaces, roadside verges, rural footpaths, parkland, sandy field margins, and garden borders. Species such as Bladder Campion, Field Forget-me-not, Musk Mallow, Yarrow, St John’s-wort, and Wild Carrot are commonly included, creating a balanced flowering display throughout the growing season.
All wildflower seed mixes are subject to seasonal change, depending on harvest, and may contain more species than listed.
