ludwigia repens?

[bridgey_c]

The lfs thought it was a lobelia, presumably cardinalis. Is it this or ludwigia repens? The more images I look at the more unsure I am.

any thoughts?

cheers mark,

I was interested because I wanted to have a go at growing this emersed.

To do this properly would I cut a couple of inches from the top of a stem and plant this in water with just the tops of the leaves showing? I surely couldnt just pop a stem in some wet substrate and cover it....

You could cut the bottom of the stem so its left with just two leaves, then plant the root, this should produce two new stems which will adapt to emmersed growth quite easily, I've grown ludwigia red diamond emmersed this way before and it's been quite a fast grower.

I'm experimenting growing a few plants emersed at the moment, first time of trying it. One of the plants is ludwigia repens "Rubin" and all I have done is place is in a glass vase with potting soil in, water to the top of the soil and planted the stems, cover with cling film and voila. It's doing very well too

thanks for the advice guys.

I have some HC and UG growing emersed in a glass vase too and they are doing pretty well. I tried a small stem of this Lud Repens in with them this afternoon and within half an hour the whole thing had wilted and lay flat so I automatically thought it was a mistake. thats why I thought they might need water to support the stem. I will try tim's method tonight with just two leaves and the roots.

cheers
