The flowering period in Switzerland is between May and July, sometimes until September. The hermaphrodite flowers are four-fold with a double flower envelope . The four petals are 18 to 23 cm long and mostly white or pale purple in color. The pods are 4 to 7 cm long.
The species has chromosome number 2n = 48.
ecology
The pollination is done by bees, flies, butterflies and moths ( Lepidoptera ). The pinnate tooth root is self-fertile .
Occurrence
The pinnate tooth root belongs to the western pre-alpine floral element and occurs in the Pyrenees , in central and south-eastern France, in the southern Alps east to Monte Baldo , in the Swiss Jura and in the Vosges . In Germany there are deposits in the Kaiserstuhl, in the southern Black Forest and on the Upper Rhine. It is also absent within the area in larger areas, but often occurs in stands with a large number of individuals at their growing locations. In the British Isles she is a neophyte .
The pinnate tooth root needs nutrient-rich, mostly calcareous, humus-rich or muddy, loose, stony loam soil . It inhabits mixed forests of beech and fir. It is a species of the Dentario-heptaphylli-Fagetum. It hardly climbs up to 1800 m.
