Small-cup daffodils possess all the same qualities as large-cup and trumpet daffodils with the difference being the size of their cups. To be classified as a small-cup daffodil, the cup (aka corona) must be less than one-third the length of the petals. Most small-cup daffodils bear only one flower per stem. Ranging from miniature daffodils standing 6 inches tall to those that tower 24 inches or more in the spring garden, these pretty plants look at home throughout the landscape. Small-cup daffodils often emit a lovely fragrance.
