East Sussex boasts perhaps the most famous garden in England - Great Dixter. Home of late gardener and writer Christopher Lloyd, Dixter is daring and experimental, but always elegant. Even if you know absolutely nothing about gardens, you'll enjoy wandering between all the different parts of the grounds, each with its own striking identity. You can see a pictoral tour on the Great Dixter website. Garden closed Monday except Bank Holidays.
Sissinghurst Castle Garden is one of the world's most famous 20th-century gardens. It is the creation of the writer and poet Vita Sackville-West and her husband, diplomat and writer, Harold Nicolson. The garden is made up of 10 distinct 'garden rooms' each with a different feel. For example the Lime Walk, designed for spring effect, the Cottage Garden using only hot colours, reds, oranges and yellows and the White Garden, with its many shades of white, greys and greens, all of which have been such an influence on gardening in the 20th century.
