The Willow pattern was originally derived from the Chinese. The first decade of the 19th century a standard pattern emerged which has been used ever since.
An old Staffordshire rhyme which serves merely a a description of the standard Willow pattern;
Two pigeons flying high,
Chinese vessels sailing by,
Weeping willows hanging o’er,
Bridge with three men, if not four,
Chinese temple, there it stands
Seems to take up all the land.
Apple tree with apples on,
A pretty fence to end my song.
