I just found info stating tomatillos are self incompatible for pollination. This leads me to wonder if the plants I buy are hybrids. I get 4" potted plants simply named green or yellow tomatillo. If I bought two of the same type will they pollinate? For example if Early Girl tomatoe needed a pollinator, another early girl wouldnt do it, that is the same type of pollen. I dont really have space for another tomatillo!
