I suspect that the waterlilies you have in mind, Rad, are Victorias. If you google "Victoria waterlily" you will find out all about them. You could probably grow them in Thailand very successfully due to the tropical climate provided they are not illegal to import. They are from the Amazon. One thing that you cannot easily glean from the online info is how thorny they are on the undersurface of the leaves and along the stems. They are like a very bad cactus and cannot be approached by swimmers. Nothing large can eat them due to the thorns. I have grown them in my pond in Oklahoma several times on a seasonal basis.
