Every spring we have daffodils growing on top of the hedges bordering the
lanes near the house. There are masses of them. But this year we've
noticed most particularly that the stems are shorter. Our theory is that
this is because they've come out earlier than usual - anyone else got any
ideas?

I've not noticed this with the daffs growing in local hedgerows, but
most of those growing around here are naturalised garden varieties
rather than true N. pseudonarcissus. However, the winter was
exceptionally mild and many wild plants that normally die down carried
on growing including a lot of wild grasses. I wonder if it's an
optical ilusion and it's not so much that the daffs are short, but
their companion plants are unusually tall? Just a thought.
