Jonquils are the March Birth flower.
Jonquil, strictly speaking, refers to Narcissus jonquilla and tends to have clusters of fragrant flowers rather than individual ones, and tube-shaped leaves rather than the flat ones of daffodils.
Its name (beloved of Scrabble players) derives from the Latin juncus, meaning rush or reed, because of the leaf shape.
When you miss someone close to your heart, Jonquils are a perfect way to remind them of you and that you wish to have them around as Jonquils are considered to symbolize remembrance.
