Oh my gosh, Cath I'm so sorry to hear about all this- what a bummer! At least you are all safe, and there was no damage to your house right? I agree with Sue, the good news is that the waterlilies will recover- and quickly. Last year we had a bad hail storm that shredded my lily pads and they looked horrible. The pads all browned and died off quickly, but new pads grew, and they were full of lush green pads again within about a couple of weeks. Those new lilies will be adjusting to being uprooted and repotted anyway, and would have went through a phase with growth focused on the roots rather than pads anyway. I hope you can get everything else cleaned up easily, and I hope some of your veggies recover too...
