How tall can a daffodil grow?

There are many varieties of daffodils and that means there are many different heights. Generally the daffodil is about 12-18inches tall. However, the Hoop Petticoat and Petite Daffodils grow only to 6 inches, and there are miniature varieties of only 2-inches. There are others that can reach 24 inches. It's said that the sandier the soil, the taller the plant. Also plants tend to be taller when a clump hasn't been separated in a great many years.
