Ornithogalum umbellatum, the garden star-of-Bethlehem, grass lily, nap-at-noon, or eleven-o'clock lady, is a perennial bulbous flowering plant, native throughout most of southern and central Europe, north-western Africa and south-western Asia.[3] In North America, it has escaped its cultivation as a garden ornamental and can be found in many areas. This plant is perennial with bulbs below ground; the bulb is 15ñ25 millimetres (0.6ñ1.0 in) long and 18ñ32 mm (0.7ñ1.3 in) in diameter. It has 6ñ10 leaves, linear with a white line on the upper surface, up to 30 centimetres (12 in) long and 8 mm (0.3 in) broad, and a scape of 10ñ30 cm (4ñ12 in). The flowers group in a corymbose raceme with 6ñ20 flowers, and are white with a green stripe outside. Ornithogalum umbellatum requires considerable moisture during winter and spring, but can tolerate summer drought. It can be grown in a woodland garden as semi-shade is preferable. It is hardy to hardiness zone 5, and can become weedy. The plant is toxic. It is used in some herbal remedies
