The National Garden Bureau was set up in the USA in 1920 to provide basic instruction in backyard gardening and create a population of gardeners. Every year they select one popular, easy to grow, widely adaptable, genetically diverse and versatile bulb (plus an annual, perennial and edible) to showcase. 2017 is the Year of the Daffodil.
Bear in mind that the information is aimed at USA growers but this link will provide some basic growing information and a slideshow of daffodil images for UK enthusiasts.
