William Henry Divers's book was published in 1909 and digitised copies are available on the Internet. One such copy can be can be viewed at the www.archive.org web-site. He also developed two varities of apple which are still available today, namely the Barnack Orange (a dessert apple) and the Belvoir Seedling (a cooking apple).

The following is an extract from the Belvoir Castle web-pages about their gardens:
The second time when Belvoir's gardens influenced garden history was around 1900. The head gardener Mr. Divers developed the concept of mass spring flower bedding which was appropriate for Belvoir as traditionally the family stayed at the Castle in the spring before going to Cheveley in Newmarket for the season. In fact, the 8th Duke commissioned the book 'Spring Flowers at Belvoir', which we are trying to get reprinted.
In Edwardian times there were 40 gardeners, now there are only three, so restoring the gardens is a slow process however the present Duchess is passionate about the gardens and their ongoing development.
