White roses are appropriate for weddings and are traditional in most ceremonies. The white, often found in the bride's bouquet, symbolizes purity, innocence and the marriage bond.
White roses are also used during Easter and as a sign of sympathy, such as after the passing of a loved one. The white represents honor and remembrance, appropriate for occasions where the giver wants to express sympathy. It also represents reverence and rebirth, an Easter theme associated with both Christianity and the advent of spring.
