Adrian Milmer with the help of the Sunday gardeners trimmed the Bay (Laurus nobilis) trees in the herb beds of the Garden to restore them to their distinctive shapes. The horticultural practice of training plants by clipping the foliage and twigs to develop and maintain distinctive shapes is known as topiary. European topiary dates from Roman times, the practice being revived in Europe in the 16th century and was seen on the parterres and terraces of gardens of the elite as well as in simple cottage gardens. Traditional topiary forms use plants trimmed as balls or cubes, obelisks, pyramids,cones or tapering spirals. Straight lines were most fashionable in 17th century gardens but there are examples of curved shapes in our garden. Other species used for topiary include Box and Yew and these can also be found here.
