Bon dia!
C. ciliata will grow too big for your container as Paul said. I would use C. wendtii instead.
No matter what species you use, you need to encourage the plant to transfer its leaves from submersed to emersed. The easiest way to do this IME is lowering the water level to the leaf level and letting it evaporate slowly. You will see the plant put out aerial leaves soon.
Maintain a fair amount of humidity. Certainly this can be accomplished via celophane paper or the like. Once the aerial leaves appear, slowly start adding holes to the paper. Your plant will adapt to your home's humidity level if it is not too low.
As Paul recommends, adding a few flakes of oatmeal will provide some CO2 for the plant that will be welcomes. |
