This plant can grow completely in or out of water. I have had it completely freeze in a chunk of ice in a pond, and it did not care. Good plant for hiding pond liners.
This is a bright green stem plant. I use it as a background plant. Fast grower. Propogation by clippings and sideshoots. I have good luck with this plant in 2.5wpg and pH of 6.6-6.8 with the addition of CO2 & PMDD.
A fast grower. I kept this in very low lighting with DIY CO2. It is doing very well. I highly recommend this plant for beginners of experts alike.
just found some today at a local nursery, traded them some aquatics for a marginal. =] edit: after having this plant for some time, i will say it is very adaptable. i think co2 is really important to this plant.. more so than bacopa m., which start to stunt quick for me when my DIY brews are slowing down.
Has done better for me in an unheated tank with good water movement. Used to root my outdoor creeping jenny (from hanging baskets) in water before realizing it could be used it planted tanks. Fast rooter and easy to propagate. Will grow above tank's water level (although weak-stemmed and will flop back into water when long enough).
