British summer time means that, from Saturday, we all have an extra hour to get out in our gardens in the evenings just as the early spring display is coming into its own. At Longmeadow, Monty Don introduces us to the coppice, a woodland area where his favourite flower, the primrose, is in bloom.As well as enjoying the seasonal colours of spring, it's time to plan the summer display. Monty sows sweet peas and gives his recommendations of what to grow to give you for colour in the garden and cut flowers for the house.
