    I am extremely pleased with my 'Egyptian Walking Onions'. They arrived in good order due to the excellent packaging. Each pot contained or than the stated number and they were in good health. The root development in each pot was just right, no signs of having just been potted up or being 'Pot Bound'. It has been a pleasure doing business with Hookgreen Herbs.
