Hartley Greens Leeds Pottery Pot Pourri Bowls. All products are made by hand to designs first used by Leeds Pottery in Yorkshire in the 18th century. Today Leeds Pottery is made in the heart of the Staffordshire Potteries, one of six towns Longton. In the Victorian era homes were not as fragrant as today and the petals of strong smelling flowers were used to sweeten up the air.
