Rosette: Anubias

Not really a rosette plant, Anubias all have a creeping rhizome that grows very slowly, throwing out new leaves as it grows. The plant is built like a tank, people report keeping them in a closet for six months in a plastic bag yet still surviving. It is also one of the most expensive aquarium plants. If grown immersed, they may produce larger leaves, and will grow faster, and flowers will produce seeds. Anubias will frequently flower underwater, but not seed. You can grow the roots in gravel, or even train the rhizome to grow on bogwood like Java fern does. Most commonly kept species is A. barteri var. nana, the smallest Anubias, which has egg-shaped leaves and makes a great foreground plant in medium-to-large aquariums. A. barteri var. barteri looks similar to the nana variety, but with bigger leaves. A. congensis, A. lanceolata and others grow very tall and make good background plants. They can sometimes be seen in better stores.
