|Ornithogalum or Star of Bethlehem are tender bulbs (damaged at temperatures under 25F) so yours will need to be dug and stored from fall through the winter months and replanted each spring. After the bulbs finish blooming the foliage will die down. When this happens, dig the bulbs and store them dry in a warm (above freezing) place until springtime. Replant when the soil warms in the spring and they will flower for you during the summer months.
