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.
sparkysko
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.
aquaphish
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.
