I found this plant in the Patuxent. It grew submersed attached to rocks and only in a really high flow area.
Looks like dill. just not very long 4-5'' tops. I suspect a Potamogeton, just have no clue what kind.
I tied it to he output of the cannister filter to replicate the high flow where I found it.
Yep , the description matches. Lets see if it survives in my tanks.
If it chooses to live on where I put it, it may make a nice "decoration" to the uglyness of the outflow pipes.
I already have Utricularia Graminifolia growing in the HOB in the nano. Looks really nice. Maybe something can be done with this one as well
