This plant is better suited as a marginal pond plant. It will grow like a weed out of the water.
High light make this plant to stay low-growing, low light make it grow very tall (5"+) as well as more brittle.
its use as food in my culture and my neighbor introduce it all over the place lol, i just go out and grab a bunch, really hardy plant and it will tilt toward the light no mater what, i lazily planted mine sideways and the next day it was facing up.
I had this plant a week and I have lots of new shoots I would say it's a fast grower in good light with co2 and ferts. When I got mine most of it was dead so I cut off the dead parts and planted the good parts and it is growing like mad. Very cool plant.
