Plant ID(thanx guys)

Ruan and Slagter,

I am not so sure about the bulb thing as sword plants definitely have quite a strong stem, which is the reason why I think it is a sword plant and not a aponogeton. Ruan, I get the idea that this was a potted plant and maybe you did not remove all the wool around the stem and that is why you are thinking that it has a bulb? Please clarify.

Then we need a name correction here: The correct name is Hygrophila and not Hygrophilia. I am not convinced that this is correct as the stem is too slender in comparison to the leaves, that is why I asked for another pic. I think this is also what WhipMe pointed out. To me it almost looks like some plant that has been grown emersed which is now all of a sudden being put under the water. Can you show us another pic please Ruan....

Kind regards,

Dirk

 

Im with the prof that the first pic is an echinodoras of some kind,(look at the bottom leaf) I would say osiris or Kleiner Bar

The second is most likely Hygrophila siamensis I say this because its the most common one we get in SA and yes it is one hell-of-fast grower(careful what you do with the cuttings it will grow just as fast in the garden!)

The third is comonly known as Brazilian pennywort and would probably grow better if you let it float closer to the lights:blink1:


thanks for the challenge, Please could you post some more pics for us to confirm what the first one is!

 

thanks, but its currently a little lightweight, it gets tumbled around if i let it float, and usually ends up with the leaves pointing to the substrate, stem in the air, caught in the flow on some random rock or mopani... thats why i stuck the tip in the substrate, it made a new leaf between yesterday/today

 

Hi guys

I noted that the Brazilian Pennywort (Hydrocotyle leucocephala) does not really require that much light to grow nicely. Of course, more light will result in better growth. In fact, there is a source on the web quoting some lux values for plants. I cannot quite figure out how they came to these conclusions. I don't know if they measured or calculated based on growth response. Either way, it is quite an interesting article, but in Dutch. Use google translator to get a "broken" English version. Sorry if this is a thread hijack!

Interesting point is that, according to this article, H. Leucocephala can grow/survive in lower light than Anubias, but the optimal growth is achieved at a lux level higher than that required for Anubias. In my experience I found that it grows very slowly when the stem is so tiny, as you get when a piece breaks off. But is really grows quickly, no matter the light, once it gets to about 20cm.
