Product Description
Yellow Rattle (Rhinanthus minor) is a charming native wildflower known for its bright yellow blooms and distinctive seed pods that gently rattle when dry. A traditional meadow favorite, this annual plant plays an important role in creating balanced, species-rich grasslands by naturally reducing vigorous grasses and allowing wildflowers to thrive.
Ideal for wildflower meadows, naturalized areas, pollinator gardens, and open landscapes, Yellow Rattle produces cheerful flowers from late spring to early summer, attracting bees and other beneficial insects. It thrives best in open, sunny locations with moderately fertile soil and is well suited for meadow restoration projects and low-maintenance garden spaces.
Easy to grow when sown at the right time, Yellow Rattle establishes well in prepared ground and blends beautifully with native grasses and wildflowers. Once established, it readily self-seeds, helping maintain long-term meadow diversity with minimal intervention.
A perfect choice for gardeners looking to create a more natural, wildlife-friendly planting with long-lasting ecological value.
