Tropica tissue cultured plants? They are available in the USA now, and there are several species that we rarely see, and several that we usually only get as emergent growth (the Tropica tissue cultured plants are submerged growth). The cost would be $12 per portion of whatever variety you want. They are all the same price. I will try to get a list put together. I am specifically after Crypt. parva, but they are out of stock, so an order will wait until they have restocked that species.
