Dividing Tropical Waterlilies

I wanted to move this N. 'Miami Rose' to another pond but decided to divide the small "pup" that I could see out of the pot first. It turned out there were three plants and it was a great example for a page here.
The big plant was removed and taken to another pot and pond. The medium one was carefully shifted towards the center of the pot without really uprooting it and reanchored. The rhizome and small tuber with plant went to the nursery.
There are other successful methods of dividing tropical lilies which require removing them entirely from their pots. When in full growth they can be divided with a knife -- just cut the crowns, soil and roots apart in chunks. Subsequent root loss will not substantially hurt the plants. They can also be bare-rooted and divided with little root loss though there is more transplant shock.
