Yellow Rattle is a native wildflower that is widely used in flower meadows, natural grasslands, and ecological gardens. It is a special semi-parasitic plant that grows on the roots of grasses and can therefore reduce the growth of vigorous grasses. This gives other wildflowers in a meadow more space to develop, helping to create greater biodiversity. The flowering period of Yellow Rattle usually runs from May to September, depending on the species and growing conditions. Most varieties flower mainly between June and August. The yellow flowers appear on upright stems and attract various insects. Yellow Rattle flowers from May to September.
