Daffodils and jonquils are the common names people use for garden forms of this genus.
The scent is reminiscent of jasmine and hyacinth; sweet and heavy; perhaps less orangey than Narcissus tazetta. Although there is a species of narcissus that specifically relates to it, the term jonquil is used for any multi-headed, single flowered narcissus.
In other words, daffodil is the official common name for ANY of the plants that fall into the genus Narcissus.
