I always think its good to visit a garden a few times a year, as different layers are exposed at different seasons, indeed in the winter months your not blinded by the 'makeup' of the garden and you can see how the plants are trained, how the beds are edged and see the skeleton of the garden.
A garden like Antrim Castle Gardens provides colour all year round through the use of evergreens, structure plants, plants with form and shape and plants which flower in the winter months....enjoy these few pictures....
