Vegetative characteristics

The large rattlespot is an annual herbaceous plant that reaches heights of 20 to 60 centimeters. The stem is branched upright, has black dashes and is almost bare.

Generative characteristics

The lower teeth of the bracts are pointed to short awning, the teeth are 4 to 8 millimeters long, the awns 1 to 5 millimeters.

The hermaphrodite flower is zygomorphic . The crown is 17 to 20 millimeters long and two-lipped. The corolla tube is evenly curved upwards, colored yellow, only the tooth on the upper lip is purple. The lower lip of the crown rests against the upper lip, so the entrance to the crown tube is closed.

The seeds are about 3 millimeters long.


The large rattle pot is a therophyte and semi-parasite .

From an ecological point of view, these are mask flowers, i. H. their often blue-spotted throat is almost closed. Pollinators are long-nosed bumblebees , and more rarely butterflies . The flowering period including the early forms extends from May to September.

The seeds are spread out as a glider pilot.


The large rattlespot occurs on meadows, semi- arid grass , forest and shrubbery fringes. It thrives best on alternately moist, moderately fresh, base-rich and nutrient-poor loam soils . This species is encouraged by intensive mowing or grazing . The Großer Klappertopf can be found at altitudes of up to 1300 meters, but is less common in the Alps.
