201 The Gardeners of the Eighth Lord Petre1 By Sir George Glutton (Ovington, Essex) The re-establishment of peace in Europe and on the high seas following the Treaty of Utrecht in 1713 led to a very substantial increase in the tempo of the introduction into this country of new species of foreign plants. In addition the scope of the gardener's activities had been much enlarged by the mastery of the art of constructing "stoves" or hothouses that did not burn down and which through the use of hotbeds of tanner's bark successfully reproduced the hot but humid conditions essential for the grow- ing, flowering, and fruiting of tropical plants. By 1730 most noble- men and gentlemen of means interested in gardening (and garden- ing under George II was coming very much into fashion) had built, or were in the process of constructing, their own hothouses, green- houses and pineries. The increase of the number of species that could be cultivated in a garden and the need of a gardener to be proficient in the management of "stoves" greatly aggravated the garden-owner's eternal problem, namely, finding a competent man with character and habits compatible with his own. When Lord Jersey set up his ananna-house or pinery at Middleton, his then gardener was overwhelmed and Jersey wrote frantically to Peter Collinson asking for help in finding a new one. Various names were sug- gested and rejected, for Jersey was patently a difficult employer and insisted, for instance, that the new gardener must be single or that if he were compelled to accept a married man, it must be clearly understood from the outset that the wife must never come near the house.2 Dr Richard Richardson of North Brierly, in Yorkshire, searching for a new gardener, had finally to accept one completely inexperienced in the management of hothouses, though anxious to learn. He was Henry Pott, formerly gardener to a Mr Masters and recommended by John Blackburne of Orford Hall, near Warrington in Lancashire, another noted botanist- gardener of the North.3 It has sometimes been said that Philip Miller of the Physic Garden at Chelsea and author of the classic Gardener's Dictionary was gardener to the eighth Lord Petre, or at least managed his garden, first at Ingatestone Hall and then at Thorndon Hall, to which he moved shortly after his marriage in May 1732.4 There does not seem to be any evidence for this and the claim may have sprung from a confusion of Philip Miller with John Miller who, as will be seen later, became gardener at Thorndon in 1742. Miller, however, was one of Lord Petre's earliest acquaintances in
