Question Questions about lobelia cardinalis (small form lobelia)

6 days ago I put lobelia cardinalis into both of my tanks. Since then it has melted with no growth in either tank (one is high light the other low). I am unfamiliar with the plant. I have seen it in many tanks online and am assuming it is aquatic. But I am starting to question that now. My questions are: Is this plant aquatic? Does lobelia typically melt then recover later? If so, how long does that take? Does it propgate like a stem plant? What are its ideal conditions?

Thank you for any And all info or experience contributed

I'm pretty sure it's a terrestrial plant that only survives under water if it gets enough CO2, ferts, and light.

Some plants are just like that. :/

Ah :( I figured and feared as much. Thank you redchigh. I will pull it and see if I can grow it outside. No point in trashing it :)

Yes, I have Lobelia cardinalis in my garden, it is not an aquatic plant. It also like sun, so don't plant it in shade.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
