Hyptis lorentziana is the actual plant. Grew moderate fast. Stems are more squarish than round. Stems are very very tuff, you need scissors to cut the stems as hand nails are not enough. The leafs are also tuff, so if fishes do peck, they have to be very strong/violent to.
Although Hyptis lorentziana is not listed the USDA plant database, there are several species of Hyptis growing wild in North America, some native and some introduced. They range in environment from being able to survive submersed to being desert species, such as Hyptis emoryi, known as "desert lavender". These plants are in the bushmint family, and can be found from Florida to California, with the native Californian, (Hyptis emoryi), being the desert species. If you find an aquatic or emersed one, give it a try in the aquarium, and post your results.
