RHS Classification System
For horticultural purposes, all Narcissus cultivars are split into 13 divisions by the Royal Horticultural Society, based partly upon flower form and partly upon genetic background. Growers register new daffodil cultivars by name and color with the Royal Horticultural Society, with more than 27,000 names registered as of 2008. Registered daffodils are given a division number and colour code.

Famous quotes containing the word system:
“Television is an excellent system when one has nothing to lose, as is the case with a nomadic and rootless country like the United States, but in Europe the affect of television is that of a bulldozer which reduces culture to the lowest possible denominator.”
—Marc Fumaroli (b. 1932)
