But, the article says that Lee Pickles successfully "overwintered" his daylilies in these water beds, so I am assuming it originally had something more behind the idea that just keeping the plants watered during dry weather? That might be a good enough reason on its own to do it, but I would love to find out what made him try it though the winter, (just absent minded like me and forgot to drain the water bed) and found out they all lived ?
