When I was a child in the 40's and 50's we rarely had cut flowers in the house. My mother certainly would never have bought any and although we had a large country garden my father thought the correct place for them was in a flower bed. The exception were bowls of bulbs at Christmas which were "forced" in the airing cupboard.
In addition to flowers and vegetables in the plot we also had trees including a horse chestnut that, it was alleged, my brother had grown from a conker. At this time of the year it sprouted "sticky buds". My mother would cut budded stems from the tree and put them in a vase in the house where we would watch the buds burst and leaves unfurl in their bright green splendour. The same was done with hazel catkin buds when we could find any. Cheap pleasures and no air mile cost.
