Gresham Lecture: British Gardens and Gardeners

Apologies in advance to those who are as passionate about gardens as they are genealogy for this diversion: Professor Sir Roderick Floud lectures on Making and Running Great Gardens 1700 - 1900 in the Gresham College lecture series.
The great English gardens are iconic, but "how much did they cost to build and maintain, who supplied their plants and equipment and what was involved in maintaining, managing and staffing them?"
Resources mentioned of possible interest to those with a gardener, horticulturalist or practical botanist lurking in the family tree include the English Heritage Register of Historic Parks and Gardens with over 1,600 sites assessed to be of national importance. Also, the Gardeners’ Chronicle is mentioned with a page from the 1870s with a long list of gardeners seeking employment used as an illustration. Find some issues of the Gardeners’ Chronicle and much more at the Biodiversity Heritage Library www.biodiversitylibrary.org/.
