Topiary is the horticultural practice of training perennial plants by clipping the foliage and twigs of trees, shrubs and subshrubs to develop and maintain clearly defined shapes,[1] whether geometric or fanciful.
The plants used in topiary are evergreen, mostly woody, have small leaves or needles, produce dense foliage, and have compact and/or columnar (e.g., fastigiate) growth habits.
[citation needed] Japanese cloud-pruning is closest to the European art: the cloud-like forms of clipped growth are designed to be best appreciated after a fall of snow.
"[3] In 1618 William Lawson suggested Traditional topiary forms use foliage pruned and/or trained into geometric shapes such as balls or cubes, obelisks, pyramids, cones, or tiered plates and tapering spirals.
The royal botanist John Parkinson found privet "so apt that no other can be like unto it, to be cut, lead, and drawn into what forme one will, either of beasts, birds, or men armed or otherwise."
[citation needed] Topiary at Versailles and its imitators was never complicated: low hedges punctuated by potted trees trimmed as balls on standards, interrupted by obelisks at corners, provided the vertical features of flat-patterned parterre gardens.
Such an heirloom, but on heroic scale, was the ancient churchward yew of Harlington, west of London, immortalized in an engraved broadsheet of 1729 bearing an illustration with an enthusiastic verse encomium by its dedicated parish clerk and topiarist.
[5] formerly shaped as an obelisk on square plinth topped with a ten-foot ball surmounted by a cockerel, the Harlington Yew survives today, untonsured for the last two centuries.
Lloyd's own timber-framed manor house, Great Dixter, Sussex, remains an epitome of this stylised mix of topiary with "cottagey" plantings that was practised by Gertrude Jekyll and Edwin Lutyens in a fruitful partnership.
He accordingly built an authentically styled Tudor village to accommodate the overflow, with an "Old English Garden" including buttressed hedges and free-standing topiary.
