I've been growning Anubias barteri plants for many years, and I get flowers regularly. Normally they are submerged. In a shallow 15 gallon tank I leave about an inch space between the water and the top of the tank. This tank is really too small for this plant. Today I noticed that a flower stalk had broken the surface of the water and what looked to be pollen grains were dusting the leaves below (click for big):
Are these flowers self fertile? If so, how do I go about pretending I'm a bee? It might be fun to see if I can get some seeds.
Another flower on the way, and a very crowded tank. The plant takes up about 3/4 of this tank. I hacked half of it away last year. Time for another prune I think.
