Sorry for all your damage Lorn. But as you say it is a good opportunity to collect important data relating to their hardiness. Wish the bulk of lilies on the market were tested like that before introduction.
I don't need bad weather to wreck my lilies. I have already busted off a few stems while dragging my hose around. I hate hearing that familiar *SNAP* when I tug on the hose. No fault but my own.
