Lobelia Cardinalis

[Ryan Young]

My Lobelia Cardinalis looks very healthy and is quite bushy, and now forms a main area of my tank. My only question is... does anyone know why/ how this plant has gone from having a nice purple under leaf to fully green?
I can rule out lighting as all my other plants which I believe to be more light intensive have flourished but cannot figure out why it has happened.
Thanks

Possibly only has the purple colour while the plant is emersed, green once adapted to submersed conditions.

Ah that would make a lot of sense!
thanks

Yep - your Lobelia cardinalis had purple leaves, because it was grown emerse......and became all green submerged. This is natural.
