Yellow Rattle (Rhinanthus minor) is a parasitic plant that can help to restrict grass growth. It can be oversown into an existing grass area, and it will start to feed off the plant roots, meaning that the grasses become less dominant, allowing wildflowers to establish more easily.ellow Rattle (Rhinanthus minor) is a parasitic plant that can help to restrict grass growth.

Yellow rattle germinates late February to early March, flowers in June, and sets seed in July. At the end of each growing season as the annual yellow rattle plants die away they leave behind gaps into which new wild flowers can establish.As a result, wild flower seed sown into an existing sward will establish more readily in areas where yellow rattle already does well.ite Selection. 1  Yellow rattle will not thrive in all grassland. 2  The most suitable sites for yellow rattle will be managed grassland of low to medium fertility that contains a balanced sward of finer grasses not dominated by coarse or vigorous grass (ryegrass, cocksfoot, tall oat-grass or couch).
