The blossoms in this division have a very unusual form. The term corona in the title refers to the cup (or trumpet) of the daffodil. In Division 11 Daffodils, the cup is split for at least one-half its length, creating an open, up-facing blossom, instead of the typical trumpet. As a result, many of the flowers look more like a Hibiscus than they do a daffodil.
Overall these are some of the showiest daffodils ever, especially for mass plantings. They are excellent as cut flowers – always a highlight in flower arrangements. Some varieties have a fragrance; I have indicated which ones by putting an asterisk (*) after the name of the variety.
