By the late 20th century, shrubs, trees and smaller plants tend to be mixed together in the most visible parts of the garden, hopefully blending successfully.
At the same time, shrubs, especially very large ones, have become part of the woodland garden, mixed in with trees, both native species and imported ornamental varieties.
The word is first recorded by the OED in a letter of 1748 by Henrietta Knight, Lady Luxborough to the fanatical gardener William Shenstone: "Nature has been so remarkably kind this last Autumn to adorn my Shrubbery with the flowers that usually blow at Whitsuntide".
[2] The shrubbery developed to display exciting new imported flowering species, initially mostly from the East Coast of British America,[3] and quickly replaced the older formal "wilderness", with compartments of smaller trees surrounded by hedges, and little colour.
The shrubbery was at first the development of the plant collector wing of the growing movement of English gardeners, who in the early and mid-18th century eagerly awaited the new seeds and cuttings arriving at London nurserymen such as Thomas Fairchild (d. 1729) from America.
[12] Its "fairly open landscape of soft lawns dotted with trees and set with lightly-wooded, sinuous shrubberies" are best illustrated in Augustus Charles Pugin's[13] watercolor view c. 1822 of the west front of the Pavilion,[14] reproduced in Nash's publication.
The winding perimeter walk circling the lawn among the shrubs and trees, enriched with island beds of herbaceous perennials, began to be laid out in 1814, with a flush of activity 1817-21.
One was Henry Phillips, who wrote in 1823 The shrubbery is a style of pleasure-garden which seems to owe its creation to the idea that our sublime poet formed of Eden.
[15]The formulas for arranging a shrubbery were founded on contemporary painterly requirements for the Picturesque; judicious contrast and variety were essential, but Philips seems to have been among the first garden writers to notice that yellowish-green leaves in the foreground seem to throw bluish green-leaved shrubs deeper into a perceived distance.
"[17] Nash was at work also on the public parks of London, devising the shrubberies of Regent's Park and of St. James's Park, where the German visitor Prince Pückler-Muskau discerned that Mr Nash ... masses the shrubs more closely together, allows the grass to disappear in wide sweeps under the plants or lets it run along the edges of the shrubs without trimming them ... hence they soon develop into a thicket that gracefully bends over the lawn without showing anywhere a sharply defined outline[18]Such precise effects were made immeasurably simpler by the invention in 1827 by the English engineer Edwin Beard Budding of the rotary lawn mower, an extrapolation of machinery commonly used to cut velvet pile.
