Plant IDs please, emersed

[foo]

Hi guys,

Here are some of the plants I have trouble identifying while waiting for the submerged growth to appear, any suggestions as to what they are are appreciated!



Plant 1) The green plant in center with small purple flowers
Plant 2) The red one just to the left and back (Ammania gracilis?)
Plant 3) The green one on the right (I suspect Ludwigia ovalis)
Plant 4) is difficult to see, but its at the top right of the picture - the one with the light purple leaves.



Plant 3) Pictured here again on the left
Plant 5) Green plant in the center of the pic

Thanks!

Ok, hopefully with some new growth I can get some answers

Plant 1 (center) and Plant 4 (top):



Plant 2 (center - red):



Plant 3 turned out to be Ludwigia brevipes / arcuata.

i had plant 3 (Ludwigia Brevipes/arcuata) befor and they just die on me:( heard u need high lights and high CO2 for that...

HI foo,

PLant 4 is definitely Pogostemon stellatus.

Plant 1 in the center is a bit difficult to see which one you mean. I see something with slighty red leaves which I think is Nesea and the one in front may be Ammania gracilis.

Plant 3 is definitely not L arcuata because that species has very fine leaves. I also do not think that it is L brevipes because that still has narrower leaves. I think it may be Ludwigia glandulosa.

If you have bought these plants from Quality Aquariums then they may be what I have mentioned because he has imported these with his last shipment.

What I would like to mention to you is that these plants look as though they  need fertilizer. Have a look at Algae Wizard's 390 l tank to see how fertilization can change what they look like, by that I am meaning my new generation of ferts. I am using these myself without CO2 and although they are not growing as strongly as Angus' plants are they certainly are growing very well.

BTW shihr, Ludwigia glandulosa very definitely needs high light and will collapse if you do not give it enough light and ferts.

Kind regards,

Dirk

Thanks for the ID's Dirk!

Plant 3 is in a emersed growth state in the original photos, because the new growth is completely different. Here is plant 3 with new growth:


As you can see, the new growth is completely different, does not look like the same plant.

It looks very similar to a plant I've had for a while which I was thinking is L. arcuata / brevipes:



As you can see, the 2 plants are very similar, except that plant 3 has slightly broader leaves (might still change if it grows closer to the lights).

It would be great if the one turned out to be arcuata and the other brevipes   What do you think?

To clarify, plant one is in the center of the picture - it's bright green with long narrow leaves that have a tendency to curl . Not sure if the curling is maybe due to too high light or lack of fertilizer.

With regards to your fertilizer, good to know you've finished the high growth formulation! I'd be very interested to know more about it, maybe you could start a thread with some details? Otherwise please PM me with details and prices!

Sorry, fixed image URLs, they were incorrect.

Hi foo,

Now that you have shown me the submersed form, I do agree that it is Ludwigia brevipes.

Kind regards,

Dirk

2 looks like Alternanthera reineckii 'Pink' (roseafolia)
