Cabomba furcata and Cabomba caroliniana are the two most common types I have found sold in the water garden industry. The plant for all intents and purposes belongs strickly in the aquarium plant industry. Why? Well it is very soft and both the stems and the foliage break easily. I do not find that these plants overwinter at all or they never seem to be around in the spring. Normally harvested and bunched in Florida shipped once is OK, if we ship it to another supplier and then they ship it to you, the plants arrive unhealthy and falling apart. Anacharis and hornwort can be damaged slightly in shipping and come back in a matter of days with new growth. Cabomba simply disintegrates. On top of that problem, they are so soft they make excellent meals for fish. One final problem, sold as a bunched plant, the rubber bands often destroy the bottom stems and the plant then float about the pond.
If you ever grow baby fish inside, this is a wonderful plant to add to an aquarium to serve as hiding space and food for fish fry.
