Blue Horizon actually has some blue in it, which is quite unusual for a daffodil (first time I've noted blue in a description). The blue color develops as the flower ages and is seen in the cup's base.
This classic cultivar was developed by David Bell in New Zealand and was registered in 1963. Thought to be seed fertile.
