Help Needed: Plant ID

[XpErIEnCe]

Hi, I have a poor eye to identify my plants from fotos or books, will like to consult all of you. My first plant for identification is this:

and

top view:

[lorba]

that should be Lobelia cardinalis in its emersed form.

[juggler]

It's listed in the AQ Flora list. The submerged form will be green. See http://www.aquaticquotient.com/aq_ga...pha&page=0

Thanks everyone. To be specific, the new leaves are light green, and grown ones are dark olive green right?? The ones I saw in shop have violet shades when the leaves are big, and the owner tell me can tie it on driftwood, issit true??

Emersed means it can even grow out of water, in a terrarium too??
