If it was labelled as "Oriental" sword, then it likely is Echinodorus "Oriental" which is a plant that appeared during in vitro culture of Echinodorus "Rose" by the Oriental Aquarium plant nursery in Singapore, hence its name. It appeared in 1994. New leaves are vivid pink and somewhat transparent, and turn to dark olive green as they mature. It remains smallish for this genus, about 15cm/6in in height and is thus very suitable in the foreground.
Okay thank Byron, Yes it was labeled as "Oriental" The new leaves are difinitely pinkish and transparent. Some more then others. Which is why I was starting to wonder. Glad to know that is normal.
