In a week I will have 50 bunches of Lobelia cardinalis small form, imported from Singapore.
I am going to great lengths to keep these plants healthy, they will be in a 55 gallon tank by themselves under 4/watts gallon and injected C02. These are the true dwarf species, which arfe only available from importers. The Lobelia produced by Florida Aquatic Nuseries is not the dwarf form.
I have found these plants to be fairly easy to grow under moderate to bright light and C02. I have lost plants fairly quickly though if they are too over shadowed, and they seem to like well oxygenated water. Maybe others experience is different?
Here is a link to Eriks article on the plant, the best written piece I have found:
