We bought this in the spring for a flower bed that's prone to winter
flooding - it's supposed to like it wet. It was doing quite nicely until
we had some summer flooding. Leaves were all nice and pert sticking out
of the water.
Then the water went. And the leaves collapsed.
The stalks seem to have broken just where they leave the tuber. No sign
of slug slime - but one of the bases looks a bit like slug damage,
something seems to have been eating into the top of the tuber. Any ideas?
