Looking for name of a tall grassy looking plant


I will look for a picture in galleries in the meantime, but I am looking for the fairly common grassy plant that people usually line on the edges of their planted tank. It gets tall enough that the top of the grass bends along the top of the water.

Not very descriptive I know, but if this rings a bell, could you please point me to the direction of the name?

The only close ones I could find are:
Contortion vals
balansae

I will find a picture now

There are other plants that will do so, depending on the height of the tank. Two of them that I can think of are Cyperus helferi and Eleocharis montevidensis (giant hairgrass).

Of the two plants Ibn mentioned, Cyperus helferi is the one that has always caught my eye in the terms you described. I believe RobertH has some at aquabotanic .

Not sure why you started a new thread for the same question...

In Sams case, it is a tall Sagittaria subulata. But I think what's more common is Vallisneria in various varieties. They are easy to grow and somewhat invasive.

I thought it was Vallisneria.

In the other post, you mentioned you wanted a height of around 16". Not that the picture you posted, the plant is more likely 24-36" tall. When I had jungle vals, they quickly started growing to the 2-3 feet range!

now i see why starting a new thread is confusing sorry!

Any chance they look good cut? If they prefer to be longer then I could just stay in habit of cutting them back.

Otherwise, I would definately need to stay with one that doesnt grow larger than 20" max.

Waterline is 15" high, and I would like to have around a 3" bend up on the top.

I am sure there is an exact match out there... or at least am hopeing

You might want to steer away from the Jungle Vals then. Left to their own devices they'll easily turn a tank into a mini kelp forest, and make the top of the tank look like someone poured spinach linguini on it. When I had Jungle Vals in a 29g tank I was pulling out 6-8 runners and clipping off 4-6" from the top of the plants every week to keep it from overwhelming the tank.

An alternative you might consider is Cryptocoryne spiralis. In my 125g tank it seems to stay around 24-26" long, but since it's not as invasive as the Val, it isn't overpowering. It takes a while for it to get established so you won't get a curtain of it overnight. And it sends out runners a lot slower.

I have that same problem with Vallis, and my African Butterfly Fishies hate it when the entire surface is entangled with dat crap. Sometimes I seem to pull 80% of the entire population out, and a couple of weeks later they are all over it again. If my wife wouldn't think that they are THE nice looking aquarium plant I would probably compost them all.

But to get back to my struggling Butterflies... I have started to just take a whole bunch of Vallis in my two hands and rip them in half. That way they still look good, but the surface is cleaned up for a while. No long-term experience yet regarding possibly faster decaying leaves, but I think this will work, besides the weekly pulling out of runners.

does the part of the plant length that bends over the surface have a problem of blocking out the light from getting to the other plants below it? or does it sway enough not to matter?

I wouldnt mind if there was even a 6-8" bend if it didnt affect the other plants.

In my tank, they definitely blocked a lot of light. It was one of the plants that was keeping my foreground Marsilea from taking off. I don't seem to recall mine swaying too much, and I did have a bit of a current at the top of my tank. I did start ripping some of hte plants in half after a while (after seenig the guy at the lfs do it before selling some I was trading in).
