the bloom is from a tropical lily named "midnight". there is another smaller one in the tank that has yet to bloom, named "green smoke"
the red floating one is a mosiac plant, ludwigia sedioides. it is nicely throwing off many other rosettes now.
and of course, lots of salvinia, azolla carolina, and amazon frogbit (limnobium laevigatum) there as well. they all grow like weeds, and have to remove several square feet each week to keep it under control. won't be long until i have to remove everything but the lily and mosiac, but the tank was made for them.
just need to get in gear and finally post my tank blog with the set-up and pictures. will get that done this weekend for people to see.
