 Culturally, the lilac carries strong associations with the rebirth symbolized in springtime. In Mediterranean countries such as Greece, Cyprus, and Lebanon, the lilac is closely tied to Easter and is used as part of religious observances there.  That is, it is an appropriate gift for a beloved who has suddenly captured the lover’s heart. White lilacs, on the other hand, signal youthful innocence, making it an appropriate gift for honouring a chaste romance.

According to tradition, a gift of purple lilacs communicates the first emotion of love.
