both jonquils and daffodils are members of the Narcissus family. But the true jonquils (Narcissus jonquilla) have round, rush-like leaves and small, fragrant early blooming clusters of yellow blossoms. Daffodils, on the other hand, have large, normally yellow, single trumpet flowers. All jonquils are daffodils, but not all daffodils are jonquils!
Jonquils are the most fragrant of the Narcissus species. The cultivation of jonquils goes far back. Roman soldiers introduced the plant into England during the early years of the Christian era. They say Queen Anne loved jonquils so much that she wove patterns of jonquil blossoms into much of her delicate needlework. And her love of jonquils inspired her to establish Kensington Palace Gardens, the first public gardens in England.
