    According to 'Daffodil' by Noel Kingsbury (published in 2013), Carlton is now considered the world's most planted daffodil.
    It is both seed and pollen fertile; used as a seed parent 5 times, as a pollen parent 7 times. Most crosses came from the Netherlands (7), 3 from England, and 1 time each from Czech Republic and USA. The latest cross resulting in a named cultivar was in 2004.
    Carlton received the RHS's Award of Garden Merit in 1995, a most prestigious award.

    Also known as Nimrod. Two-toned yellow flower has a vanilla-like scent. An excellent perennializer that does well in the south. Some sources say this cultivar is the world's 2nd most numerous daffodil. Can be forced and then set out into the garden for blooming in subsequent years.
    Carlton increases vigorously.
