Ornithogalum umbellatum L.
Star of Bethlehem, Grass Lily, Nap-at-Noon, Eleven-o’clock Lady, Star-of-Bethlehem
When this lovely little plant popped up in the middle of my lawn, I carefully mowed around it three times. Then my nephew mowed the lawn. He didn’t get the memo! Oh well, maybe it’ll be back in the spring. Star of Bethlehem is native to southern and central Europe, northwestern Africa, and southwestern Asia. In North America it escaped cultivation and is now naturalized. In Maryland and Pennsylvania, it is reported to be invasive. It prefers new forests, floodplain forests, and wet meadows, yards, or gardens.
