Lobelia cardinalis (Cardinal Plant)

Hello everyone,

First trip to the LFS in a while yesterday. Picked up some more
ottos and a second Bolivian Ram (soo cute!)

Also stumbled across a potted plant in one tank labeled
"Cardinal plant - Lobelia cardinalis". It has some pretty cool leaf
coloration, kind of a purpleish color.

I searched on google some for both the common name and the
scientific name, and found lots of links for a non-aquatic plant. Some
of links claims that it grows equally well in water and out. Anyone
know for sure?

The tag (From Florida Aquatic Nurseries) claims "True Aquatic,
Foreground, Moderate Light", but mentions nothing about fertilizing.
I've got it in my 20g tank with 40W of flourescent light and DIY CO2. I
dose Kent Freshwater Plant Supplement and Flourish Trace weekly (or so -
I'm a tad random about it these days), but also feed some plants via
substrate tablets. This guy looks like a root feeder - anyone know for
sure?

Thanks!

A Pope has a Water Cannon. It is a Water Cannon.
He fires Holy-Water from it. It is a Holy-Water Cannon.
He Blesses it. It is a Holy Holy-Water Cannon.
He Blesses the Hell out of it. It is a Wholly Holy Holy-Water Cannon.
He has it pierced. It is a Holey Wholly Holy Holy-Water Cannon.
He makes it official. It is a Canon Holey Wholly Holy Holy-Water Cannon.
Batman and Robin arrive. He shoots them.

I see alot of it, atleast in two LFS specifically, and both were gorgeous
little plants... I like purple so it caught my attention from the
beginning... I asked, undemanding, low light to moderate light plant, any
water, any temp, it'll grow....

I asked her how it would do in an injected tank, she said, I wouldn't
because it may grow too long or too big... but she was smilin' so I'm
guessing that was tongue in cheek..

injection ::-)

I have looked a bit on this plant as well.  I think you will be a
bit "surprised" how it does (or doesn't) in the aquarium.   a href="http://www.aquazoo.co.uk/Page.cfm/Type=Plants/PlantID=89"Lobelia
cardinalis/a as is available in most stores is grown either hydroponically
or emersed.  Generally this is done because it looks good when it
is all purple and scarlet.  In the aquarium, it generally turns light
green even under  intense lighting, which it does require.
pFor reds and purples in the aquaria, a "general" rule is that you need
strong light.  With strong light comes other "necessities" like CO2. 
If you really want a true aquatic plant with purple coloration, I recommend
something like  a href="http://www.aquabotanic.com/abstore/en-us/p_9.html"Ludwigia
gladulosa/a and for red/puples, try a href="http://www.dennerle.de/pflanzen/Pflanzenbilder/A04.jpg"Alternanthera
reineckii/a.

I grow them in my garden outside. I wonder tho if they will do well
submerged in the long run. Keep us informed.

Yea, the tank in question produces beautiful scarlet red sunset hygro,
and even gets bacopa to turn a touch red. But it's been about a week or
so now, and the purple leaves have already mostly dropped off. It
doesn't appear to be dying just yet, but if it's growable emersed, it
could take a few weeks.

All in all, kind of a bummer that it probably won't work out - it looked
great at the LFS. I'll post later on the topic, once we see how things
are actually going to work out. I won't mind a bit if it grows green
::-)

Lobelia is only red or purple when it grows above the water.
Underwater the red emmersed leaves fall off or turn green, and all new
growth leaves will be green. It is still a neat plant. It is a fore
ground plant if you keep it trimmed low to the ground, otherwise it
will get fairly tall. There is also a true dwarf variety that is
imported into the USA. Florida Aquatic does not grow it.

Lobelia need 2 to 3 watts of light per gallon of water, and should not
be shaded by other plants. It will rot in the substrate pretty easy if
the substrate becomes too dirty and oxygen is too low. This plant has
been used in dutch aquariums for 50 years or more.

There is a lot of detailed discussion of this plant in my forums. It
is also a terrestrial plant. I have it in my garden where it is 3 feet
tall, leaves all beet red and its flowers are bright fire engine red.
Its an amazing plant.
