I leave my Lavenders unpruned during the winter, birds enjoy the seeds
and the cover. When at last I do prune them I throw the prunings down
on the greenhouse floor, untidy maybe but the smell as you move about
the greenhouse in the winter is wonderful

I did the flowers for someone's wedding last summer and we strew lavender
heads on the entrance to the church for people to walk over. It was
gorgeous!
bay leaves are good and walnut leaves all much better than man made
perfume, in my opinion that is, bonfire smoke, grass the list goes on
and on :-)
