From the book ‘culture of flowers’,
The English word ‘graden’ continues to mean an enclosure in which the soil has been worked over for planting plants of various kinds. It probably comes from the northern French form of ‘jardin’, but it also links up with the Teutonic roots of the word ‘yard’. The term again refers to an enclosed space, being used by Americans for what in England would be a garden and where a yard tends to be an uncultivated plot, a goods yard, a courtyard, and so forth; the Anglo-Saxon term was ‘wyrtzerd’, literally wort-yard or herb-yard. That was often seen as walled, which continued to be very much the sense of ‘gardin’ in Chaucer’s ‘Romaunt of the Rose’ dating from fourteenth century. But the concept goes back beyond the Judaeo-Chrishtian tradition of the walled garden of paradise and the imagery derived from it.
