Easter is a Christian holiday that celebrates the resurrection of Jesus Christ. It is often celebrated with flowers, and three popular Easter flowers are the LILY, SPIREA, and CALLA. The LILY is a trumpet-shaped flower that is often white or pink in color. The SPIREA is a flowering shrub that has clusters of small white or pink flowers. The CALLA is a white flower that is shaped like a trumpet. All three of these flowers are popular choices for Easter decorations and bouquets.
