Hallo from Italy and a good summer to everyone,
finaly I was able to find the rare Pontederia (Eichhornia) natans and my opinion is that the plant cultivated in the past was mostly P. diversifolia.
For exemple in old dutch books and magazine as the famous Arend van den Nieuwenhuizen Das wunder im wohnzimmer it is showed a green plant identical to P. diversifolia.
This P. natans is mostly orange even under normal light condition.
