Great Dixter is a historic house, garden, centre of education, a place of pilgrimage for horticulturists from across the world, and remained the lifelong family home of the late gardener and writer Christopher Lloyd.

The green-fingered expert visits Gravetye Manor in West Sussex. Gravetye was once the living laboratory of horticultural innovator William Robinson and ornamental flower gardens compete with his beautifully designed walled kitchen garden, which supplies the hotel's restaurant. In spring, Carol delights in the wildflower meadows covered in blankets of daffodils, crocus and snowdrops and in the summer, revels in the beauty of the ornamental flower garden. The autumn brings dazzling displays of colour among the trees, while in winter the gardeners spend their time gearing up for the year ahead.
