cardinal plant

From TROPICA website:

In the nursery this plant is cultivated in marshy conditions, forming dark-green leaves which are purple underneath. In aquariums the leaves turn a beautiful shade of light-green. It needs intensive light to thrive. Widely used in Dutch aquariums in so-called ''plant streets''. In open aquariums it grows above the water surface, where it forms very beautiful scarlet flowers and the leaves regain their colour. Can be used in garden ponds.
 
I understand how the plants are grown in the nurseries. I'm saying that the purple color the plants show in nursery 'marsh' conditions does not occur in wild-type plants, which also grow in 'marsh' conditions, leading me to believe the purplish nursery plants are a cultivar. Upon further research, I found [url=http://www.bbc.co.uk/gardening/plants/plant_finder/plant_pages/495.shtml]this[/url] image of a purple cultivar called 'Queen Victoria'.

Do you know that the aquarium plants are a dwarf variety, or do you say that simply because they are small? I believe the small size of aquarium-grown plants is due to their being grown in unnatural conditions, not to genetics.

Sorry about turning this thread into a botany debate! :D
 
I have one already :), its sitting in the plastic pot so I was unsure if to return it or not if it wasn't aquatic.

But seeing it can become emmersed and survive, I'll find a tank to put it in :).
