I find it very strange that the same plant can vary so much in color. I have one bunch of LA that has been in my tank for a couple of monts. I bought it because I wanted a vibrant purple/pink/red contrast to all of the green in my tank. Well after a few weeks I found out that not all LA turnes this color. This specimin is a very robust limey green with 2" or so diameter stems and leafs. This plant is almos all the way to the surface in my 23" tall tank with no variation in leaf color from bottom to top.

Now I recently traded for some of the more "hypercolor" LA. This specimine has been in my tank for a few days and is roughly 5" or so from the substrate and is already showing some redness in the leaves. Along with the redness this plant also differs from the non "hypercolor" in that it is more yellow or not a vibrant green as the othere LA.

I leaned out my nitrates trying to ge the origonal plant to color up to no avail. I think some ppl believe that this plant will only color up with low Nitrates. I am going to prove that this is not true and after only a few days I can see that it will not be hard at all.

Also does anyone know what is the deal with the variance from one plant to another (cavan)???:D

When get home ill post some pics.

Here are pics to help display what I am trying to convey.

This is the origonal Aromatica nice, green but no red hue whatsoever.


The new Aromatica much lighter in color but already showing some redness.

My thoughts exactly.

From the experience I have had with this particilar variation there is no way it is going to turn red or any shade other than green no matter what. I have tried leaning nitrated down to 5ppm (with a un calibrated test kit) but still... dosed more iron and I have 130w of pc light and 36w of no t5 light over the tank (37g 23" tall) so I think that would be classified as higher light.

LA is a strong flower reproducing plant so there is plenty of genetic variety out there. I think you are quite right in that most of the color is genetically predetermined. However, low nitrates, high light and high iron will definitely bring out the reds in any variety.

I find it a bit odd that the green LA has no variation of color at all, usually the top and bottom of the leaves are a different color.

Im betting the farm that the origonal LA will not change at all and the new LA is going to have purple undersides to the leaves within a week. All with the same parameters.

Then after this hopefully happens I will see what intensifies/dullens the colors.

I need to calibrate my nitrate kit...

I would be more then happy to. What are you tank params/specs?

when the weather breaks (freakin cold this week)
would you be willing to send me a few of the green stems and I can try to color them up?
I could post pics / parms / regime / handle shipping and stem costs etc.

as an experiment. I think I can coax color out of it.

I dose your normal EI (nitrate, potassium and phosphate) with Excel when I feel like it normallay after water changes. My micros come from either TPN or Flourish, again whichever I feel at that time.

Dont you think that me having two sets of LA in the same tank one with no color and one with color kind of already prooves this unnessicary?

OR are you saying that the shock treatment is what this plant needs to get some color?

I'm hoping I can demo this when I get some of bsmith's green L.aromatica -- I group this stem in the category that responds well to a shock, not a bad shock but a rapid change in parameters maintained for a while. I suspect that I can drop it into a tank with clear water (low TDS and no ferts) then starve it a bit. Before it suffers bring up macros / micros / GH in a planned regime. It should respond with color. We'll see. Experimentally I have done it with a few sp. and a 3rd party test subject would be cool. Hopefully I can have it remain green for a while, then purposely switch its color. None of this is earthshaking or original, I just hope to demonstrate it as a repeatable process.

to tackle this subject :

and so forth.

I don't know man I think you will have your work cut out for you...

New stuff coloring up nicely (less then a week in the tank).



Old stuff nice and green still no color (a couple of months in the tank).

I think that these two plants would do the same in anybodys tank. There just two totally different variations. My tank is not special at all.

Now, trying to test the discus poop theory any ideas on that one? :D :rolleyes:

I dont have the means to get quite so scientific on this LA. But it is nice to know some of the same experiences have happened occured with different sp.

Genetic variability could explain this, as an example:
I grew a crop of 500 poinsettias of all different varieties, however some had to be propagated by cutting because it was the only way to keep the traits. The desired trait was a product of mutation and the chances of another mutation were very slim, so they propagated thousands of the same plant by cloning from one original plant.

I believe that most aquatic plants are probably reproduced by cutting, but who knows. That probably means some LA comes from a stock that is primarily green, and some comes from a stock that is more colorful.

BTW i have had the same experience as BMS here, two diff stocks in same tank one colorful one not... But i chalked that up to buying one as Hippuroides and one as Aromatica (Which was sold as the greener one)

Seeing is beleiving. ;)

I look forward to seeing what color you can coax out of it.

well, I got the stems today (thanks). You aren't joking, this stuff is green! I'll still see if I can squeeze color out of it.. All the years I've kept and traded LA, I haven't come across this one. Shows what I know. :)

I'll get a space cleared out for three groupings and get baseline pics posted this weekend.

No, as you can see from the pics there still all green. Im not sure if the plants are "stunted" I will say though that the green aromatica does not grow half as fast as the colorful plants, again as the pics show.

is there a reddish blush under the leaves of your 'green' LA? the ones you have sent me are showing that but for the most part not colorful. And they are stunted :(

I'll get pics up tonite, sorry I've been slacking so much on this. I'll try to point out one main difference between yours and mine, the number of leaves per whorl. I know I've seen discussion on this in the past but cant recall where. My Limnophila aromatica has a lower number of leaves per whorl - more than Limnophila repens 'mini' but fewer than the two samples you sent me.
