FWIW

I started with some cuttings of the small form Lobelia close to a year
ago from someone on the APD list. I have been growing it since in two
of my tanks, one has 4WPG (CO2, lot's of nutrients etc.) and the other
is a low light 1.2WPG with no liquid ferts, just a very rich
substrate. Both tanks are growing this plant very well and I often
remove baby plants to propagate or trade. I have always cut them back
when they get too tall and replant the tips, have never had a single
specimen die on me yet. Actually I was surprised to see that growth
differed little between the high and low light tank.

Based on my experience I'd have to say it's an aquatic plant, grows in
both low and high light tanks. And seeing both of these tanks have a
rich substrate (fluorite, flourish tabs, mulm and peat) perhaps
prefers a rich bed or is a better root feeder than leaf feeder. I have
found it very easy to grow but am scared to call it easy after reading
some of these posts. Many imbalances have occured in the high light
tank from messing around with ferts and figuring out the best balance,
never effected the Lobelia in any way other than green spot on the
leaves. Perhaps the transition from emerged to submerged is somewhat
harder with this plant. The one's I received were already submerged,
perhaps that's why I didn't have any problems with it?

Here's some photos of the Lobelia in the high light tank:

Hope that helps, this truely is a nice plant and well worth trying it
again if you can.
