Last year for Mother's Day Nigel promised to build me my very own eight by twelve foot greenhouse.  I have often lamented the loss of the little potting shed I left behind when we moved up to the Garden Centre, 17 years ago.   It's a funny thing; I have two fairly large greenhouses at the Garden Centre, right? But it's not the same as a wee place of your own, where you can go and poke about.  A personal greenhouse is an amazing place.
