Occurrence

The Real toadflax is commonly found on warm slopes. It is in this way a typical plant debris, she loves loose, rocky and sandy soil.

The Real toadflax is in Central Europe a so-called Apophyt, as originally native to the coastal vegetation type changed to anthropogenic locations than in central Europe about 7,000 years ago, forests were cleared by people in order to make room for farmland. These locations were more open than most natural and they were disturbed regularly and thus offered the genuine toadflax optimal living conditions.

Ecology

The Real toadflax is a is a 1 m deep rooted root buds - Geophyt or Hemikryptophyt.

The flowers are "Genuine Mask flowers " and rich in flavones; they are bright yellow and have orange juice times on the lower lip. The lower lip is pressed by a spring hinge to the upper lip and so can only be opened by bumblebees and larger wild bees. This is called the bloom, therefore, a " power flower". The Haarwülste the lower lip are a seal and guide line to the nectar, which is located in the 10-13 mm long Kronblattsporn. The flowers are self-sterile but homogam. Pollinators are particularly bumblebees and other langrüsselige bees, butterflies go through its narrow snout to the nectar. Bumblebees commit " flowers slump " by bunching of the spur.

The flowering period extends from May to October.

Especially impressive is the mutant " Peloria " which is a radiärsymmetrische, instead of a dorsiventral flower has 5 instead of 4 stamens, owns and in which all five petals are spurred. Because of the strong outward deviation presented Linne ' the plant in its own genus Peloria. Genetically the difference, however, only that of the mutant in a gene is blocked by methylation of a single DANA block.

The fruits are capsules as pores wind and animal shakers. The flat, hautrandigen seeds spread as a glider and water Hafter, but also ants propagation takes place. There is a rich seed production of up to 32,000 seeds per plant. Fruit ripening from July to September.

Vegetative reproduction occurs by stolons and root sprouts.
