Short answer is I don't know why.
Ornamemental hyacynth bulbs are conditioned in a freezer to make them flower
early for Christmas.
An Italian friend with a very sheltered Italian garden- warm and lowish
humidity in the winter says she can't get bluebells to grow.
I suspect its a combination of soil and climatic conditions maybe overwinter
that has caused the glut.
After all why should they prefer to grow in woods in the first place?
As a digression on the same theme badger territories are large enough to
ensure a good supply of earthworms. The worms only come to the surface over
a narrow range of temepratures and humidity, so the badgers need a subtle
variety of locations to ensure a regular supply.
I think plants respond to similar subtle variations.

this year, after never having had any bluebells in my garden, I now
have
loads, and so does my neighbour!

Why did this happen? Seems strange to go from none to loads in one
year,
anyone else seen this?

Mike

Me too .... I was very surprised to see loads of them in my garden ,as
far as I remember they were never in flower before ...




Which type are they? If they are the English ones then someone may want
some
If they are the Spanish incomers then dig them up and throw them on the
compost or whatever before they cross with our native ones.
