I don't think so, mine has gone through stages of being very red, purple adn green depending on location, lighting and nutrients dosed. Much like Stellata, L. Cuba and similar plants, the red colors come out more strongly in different conditions. There is also white balance to consider from the camera, some of the pictures here are rather warm in tone, making the reds stand out even more.
The plant identified by Kassalmann as Limnophila aromaticoides (our former "Gratiola") was the only one that was flowered. It wasn't compared directly to a specimen known to be L. aromatica.
Limnophila aromatica, the deep purple variation from Oriental Aquarium, has different growth habits and coloration from the former plant. No one in the U.S. has flowered L. aromatica, L. aromaticoides, and L. hippuroides (another OA plant) together for a flower comparison to see if they are all actually the same species. However, it wouldn't surprise me if they were considering the extreme variation in the fine leaved Ludwigia inclinata group (Cuba, Pantanal, Araguaia, etc).
