Is Emersed growth plant or submersed growth plants are best

If we have to choose either one of them, we recommend you to purchase the
plant in emersed form and grow it in the aquarium to develop submersed leaves,
since it is easier for the plant to adapt to the aquarium environment and
therefore the risk of unsuccessful growth is minimized.

In general, submersed leaves can easily get damaged during transportation and
they may often be unable to adapt to the changing environment.  The submersed
leaves grown from a plant in emersed form usually grow vigorously because of
the plant's nature to keep up with the sudden change in environment.

Furthermore, the chance of having the trouble of a melted bottom stem is lower
in the emersed form of stemmed plants.  When you use imported aquatic plants
sold in emersed form, you have to be careful of residual pesticide.
