I was able to find information about the hotel we stayed at, and thought that - since they include the gardens in their name - I may find some information there. But no such luck. The only mention on the various sites about the hotel (which is called "The Beeches Hotel And Victorian Gardens" by the way) was a brief mention in the first paragraph of the following piece of text:
"A few minutes’ walk from the centre of Norwich, the hotel and gardens are well situated for exploring the fine city, with the comfort of country house accommodation.
A warm welcome awaits you at reception. From the moment you check-in to the time you check-out you will be looked after by a team of caring, professional staff. Their job is to ensure your complete satisfaction during your stay. The hotel consists of a total of 43 rooms contained in 3 seporate, characterful Victorian houses, with a modern extension to the main Beeches building. The Beeches is only a 5 - 10 minute walk to the city centre, and is one of the closest hotels to the new Chapelfield Shopping Centre."
I was beginning to think my search would be fruitless when I found this:
Just 600 yards from the City Centre this splendid Victorian Garden is a hidden treasure. Reminiscent of the Secret Garden it has a tranquillity which is perfect to take you away from the bustle of the city. The garden was established 140 years ago in a 3 acre abandoned quarry.
Visit the Plantation Garden's website."
The address and discription found on the website lead me to the conclusion that the "Victorian Garden" mentioned in the name of the hotel and "The Plantation Gardens" are the same garden.
While browsing the website for The Plantation Garden, I found a link leading to a page telling the history of the garden. The following is what was on said page:
In 1856, a prosperous upholsterer and cabinet maker living in Norwich, took a long lease on an industrial site just outside the old City walls. His name was Henry Trevor, and for the next forty years, he spent considerable sums of money and much effort transforming a chalk quarry into a magical garden.
In many ways, Henry Trevor's garden was typical of Victorian taste and technology. He built a fountain, terraces with balustrades, rockworks, a Palm House, and a rustic bridge.
He planted elaborate carpet beds, woodlands and shrubberies. He designed serpentine paths to conduct the visitor along circular routes, and he built and heated several greenhouses with boilers and hot water pipes.
Henry Trevor, however, was also a man of strong personal tastes. His "Gothic" fountain is unique, and he displayed great enterprise in using the fancy bricks from a local manufacturer to create medieval style walls, ruins and follies. Within less than 3 acres, he established a gentleman's residence and garden that reflected in miniature the grand country houses of the Victorian period. Visitors were frequently welcomed in the garden by Henry Trevor, for he was always ready to allow his garden to be used for charitable causes.
After the 1939-45 war, the garden was virtually abandoned. Fortunately, much of the structure has survived, and is gradually being restored by the The Plantation Garden Preservation Trust. The first task of its members was to clear a forest of sycamores and a blanket of ivy to reveal what had become hidden during the past 40 years.
Since then, they have restored the flowerbeds, fountain, balustrading, Italian terrace, rustic bridge and in 2007, the Gothic alcove.
Detailed information about the history of the garden can be found in The Plantation Garden, A History and Guide by Sheila Adam, 1998."
