Wildflower Meadow Seed

Yellow Rattle (Rhinanthus minor) is an essential annual wildflower for creating and enhancing wildflower meadows in low-fertility grassland. Recognisable by its bright yellow flowers, this meadow plant is semi-parasitic on grasses, helping to reduce grass growth and open up the sward, allowing a greater variety of wildflowers to establish and thrive.
