yeah, that's a way different bacopa than what I have, jpappy... but that looks nice too. Mine flowers with white flowers, but not nearly as many as that, and very very seldomly.
there are also some pics of what I think is the same bacopa, in Hydrophyte's tank here http://www.aquariacentral.com/forums/showthread.php?t=213440&page=4
Yeah, that's actually australis...oops. I assume different species will spread and flower differently. Is that monnieri in your tank?
