Experiments of Joseph Gottlieb Kölreuter
Concerning the experiments of the German botanist Joseph Gottlieb Kölreuter, we need to highlight some facts:

-Firstly, in Germany the D. purpurea exists and can be very common.

-D. purpurea is a highly pioneering plant, which means that its seeds accumulate (in this case, especially carried by the wind) for decades, awaiting an event of soil cleaning to germinate.

-Therefore, it is practically impossible to guarantee that, when sowing Digitalis thapsi in this country, the land is not already full of D. purpurea seeds.

-Throughout the generations, hybridization will be produced and, in that field, it will be certain that D. purpurea genes will win the competition. 83.132.96.185 (talk) 22:28, 23 August 2021 (UTC)
