Madonna Lilies have since time immemorial stood as a symbol of purity, innocence, hope and grace. The Madonna lily has been patronized by artists and sculptures and often been used in reference to Mary. There are several conjectures on the relation between the white lily and Easter.
One of the parallels between the Resurrection of Christ and the Easter lily is the way the flower blooms. The bulb grows by water bodies, deep beneath the soil damp from water sprays. While there is no observable activity above the ground, the bulb grows hidden from sight and then one day, suddenly shoots up and blooms.
The imagery is akin to the manner in which Jesus rose from his tomb.
These days, the Bermuda lily has replaced the Madonna lily as the Easter lily since the former does not force well and is a temperamental flower which does not always bloom during Easter. Throughout regions celebrating Easter, one can find altars and houses adorned by the pristine Easter lily.
