I see that among the material offered in the latest BX is Arisaema triphyllum, a North American native known as "Jack in the pulpit." I remember reading, I think in the NARGS Quarterly long ago, that A. triphyllum shoiuld not be planted in a garden where other Arisaema species are grown (at least, outside its native range) because it can carry a virus which it tolerates, but which is harmful to related species. Does anyone know more about this?
