The cottage garden is a distinct style that uses informal design, traditional materials, dense plantings, and a mixture of ornamental and edible plants. English in origin, it depends on grace and charm rather than grandeur and formal structure. Homely and functional gardens connected to working-class cottages go back centuries, but their stylized reinvention occurred in 1870s England, as a reaction to the more structured, rigorously maintained estate gardens with their formal designs and mass plantings of greenhouse annuals.
The earliest cottage gardens were more practical than today's, with emphasis on vegetables and herbs, fruit trees, perhaps a beehive, and even livestock. Flowers, used to fill spaces, gradually became more dominant. The traditional cottage garden was usually enclosed, perhaps with a rose-bowered gateway. Flowers common to early cottage gardens included traditional florists' flowers such as primroses and violets, along with flowers with household use such as calendula and various herbs. Others were the richly scented old-fashioned roses that bloomed once a year, and simple flowers like daisies. In time, cottage-garden sections were added to some large estate gardens as well.
Modern cottage gardens include countless regional and personal variations and embrace plant materials, such as ornamental grasses or native plants not seen in the rural gardens of cottagers. Traditional roses, with their full fragrance and lush foliage, continue to be a cottage-garden mainstay — along with modern disease-resistant varieties that retain traditional attributes. Informal climbing plants, whether traditional or modern hybrids, are also common, as are the self-sowing annuals and freely spreading perennials favoured in traditional cottagers' gardens.
Cottage gardens, which emerged in Elizabethan times, appear to have originated as a local source for herbs and fruits. One theory is that they arose out of the Black Death of the 1340s, when the death of so many laborers made land available for small cottages with personal gardens. According to the late 19th-century legend of origin, these gardens were originally created by the workers that lived in the cottages of the villages, to provide them with food and herbs, with flowers planted in for decoration. Helen Leach analysed the historical origins of the romanticised cottage garden, subjecting the garden style to rigorous historical analysis, along with the ornamental potager and the herb garden. She concluded that their origins were less in workingmen's gardens in the 19th century and more in the leisured classes' discovery of simple hardy plants, in part through the writings of John Claudius Loudon. Loudon helped to design the estate at Great Tew, Oxfordshire, where farm workers were provided with cottages that had architectural quality set in a small garden—about an acre—where they could grow food and keep pigs and chickens.
