How can I divide a vertical water lily rhizome?
I have recently acquired a dwarf water lily of unknown variety for my first and brand new water garden. The rhizome is almost a foot high with at least six side shoots as well as the crown. Unfortunately, because of its height, the crown is only just underwater, so my question is will it be OK to cut off the top six inches and attempt to grow that as a cutting, maintaining the original plant in its intended position. I've searched the internet for info, but only find info on dividing horizointal rhizomes, not vertical ones.

PPS Maybe photo uploading sideways is trying to tell me something!
