Kleiner Klappertopf

<em>Rhinanthus minor</em>, the common yellow rattle or little yellow rattle, is a hemiparasitic annual plant in the family Orobanchaceae. It is native to Europe and parts of western Asia, occurring in traditional hay meadows, calcareous grasslands, moorlands, and other nutrient-poor grassland habitats. The species attaches its roots to those of neighboring grasses and extracts water and nutrients from them, thereby weakening grass competition and promoting the establishment of a more diverse wildflower community. This ecological role has led to the deliberate introduction of <em>Rhinanthus minor</em> in grassland restoration projects across Britain and Europe. Plants typically reach 10–50 cm in height and bear inflated calices enclosing yellow tubular flowers, which rattle when the ripe seeds are shaken — the origin of its common name. Biological traits such as precise average lifespan measurements and body weight data remain poorly documented in consolidated scientific literature. Seeds germinate only in the presence of host grass roots. The species is assessed as Vulnerable, reflecting significant declines caused by the widespread loss of traditional hay meadow management and the conversion of grasslands to intensive agriculture across much of its European range.
