Digitalis purpurea M gene determines the production of a purple pigment, a type of anthocyanin. The m gene does not produce this pigment.

Lastly, the W gene makes the pigment be deposited only in some spots, while the w gene allows the pigment to be spread all over the flower. This combination leads to four phenotypes: Digitalis purpurea Digitalis purpurea (foxglove, common foxglove,
