The bathroom has taken on the air of Miss Havisham's en-suite.
I am having a go at preserving some of my mother's beautiful hydrangea heads. Sarah Raven reccomends conditioning the heads (which are really bracts, rather than flowers) by placing the stems in boiling water for 30 seconds and then laying them in a bath of cool water overnight.
The next day, I shook them off and they are now standing in a solution of 1 part glycerin to 2 parts hot water. Once they have sucked it all up, they should remain soft and retain their colour. This might take as long as a month, but if it does, my heads ought to be ready to make into a Christmas wreath. Forward planning, people (she says, ducking...).
