Rhinanthus is a genus of annual, semi-parasitic wildflowers called rattles, such as Yellow Rattle (R. minor), which grow in meadows and grasslands and draw some nutrients from the roots of neighbouring grasses. They are grown mainly in wildflower meadows, and they need open, low-fertility grassland to thrive.
