Recently introduced some white flowered and yellow centered water lillies to my newly purchased lake (old gravel pit in Southwestern ,Ontario). I added these water lillies around two islands and a small clay outcrop in the main body of water in 2-3' of water depth. My question is most of the lake (old gravel pit) is only 5-7 feet deep, will these native water lillies move out into the deeper water and take over most of the lake that we plan to use for recreational use as well as future large mouth bass fishing. Or will the deeper water define the growth area for these white water lillies. Any help would be greatly appreciated or comments from people who already have this lilly. The lilly was taken from a pond that these lillies were growing in less than 4' of water depth. Thanks in advance.
