Farthest of all, the Circular Garden is also known as the Sunken Garden or Pearl Garden because of its shape. Originally called the Butterfly Garden, its amphitheater like structure has rings of flower beds that are planted with fragrant varieties of stock, phlox and pansies of different colours, marigold, viola, alyssum and many  others during summer annuals.

A bubble fountain concealed in a circular pond forms the centre of this garden. The pond has Lotus flowers and is edged with calendula and marigold.

It is interesting to see an Apiary near the Circular Garden.
