I finally found somewhere it was legal to take some water illies here in florida well not completely legal it was a state park but they were tredging out a boat ramp and tareing out the water lillies so the park ranger said I could have all I wanted. I took 2 plants with about 4 -6 leaves on them and a couple flowers. The root ball on these thing are about three time the size of the plant. My question is can I trim the roots down with out affecting the plant. Also do they have to be planted or can I let them float in the water.
