A single Easter Lily. With its beautiful trumpet-shaped blossoms, the Easter lily is said to symbolize purity, hope, and life, the spiritual essence of Easter and all the promises of spring. Easter lily blooms last longest indoors if given bright, indirect light and cool (40-50?F) temperatures at night, and daytime temperatures below 70?F. Keep the soil consistently moist but never soggy and never let the pots stand in saucers of water.
