What is a jonquil?
In some parts of the country any yellow daffodil is called a jonquil, usually incorrectly. As a rule, but not always, jonquil species and hybrids are characterized by several yellow flowers, strong scent, and rounded foliage. The hybrids are confined to Division 7 and the term “jonquil” should be applied only to daffodils in Division 7 or species in Division 13 known to belong to the jonquil group.
