Heavy Clay Wildflower Seed Mix

Transform heavy clay soil into a thriving wildflower meadow with our carefully selected Heavy Clay Wildflower Seed Mix. Specially formulated for moisture-retentive soils and areas prone to seasonal waterlogging, this beautiful blend contains 24 British native wildflower species chosen for their ability to flourish where many other wildflowers struggle.

Perfect for low-lying gardens, wet meadows, poorly drained ground, field margins and clay-rich soils, this predominantly perennial mix establishes a long-lasting display that returns year after year. As the meadow matures, it produces an ever-changing tapestry of colourful flowers while creating an invaluable habitat for bees, butterflies, hoverflies and countless other beneficial insects.

Designed for Wildlife

A healthy wildflower meadow is one of the richest habitats you can create for pollinators. This diverse mix provides a continuous source of nectar and pollen from spring through to autumn, helping to support Britain's declining bee and butterfly populations throughout the growing season.

The wide variety of flowering species also offers shelter, food and breeding habitat for many insects, birds and other wildlife, making it an excellent choice for gardeners who want to increase biodiversity while enjoying a spectacular natural display.
