Ornithogalum umbellatum (Star-of-Bethlehem, Grass Lily, Nap-at-Noon, Eleven-o'clock Lady), is a perennial bulbous flowering plant, native throughout most of southern and central Europe (north to Austria and Belgium), and in northwestern Africa and southwestern Asia. 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 15-25 mm long and 18-32 mm diameter. It has six to ten leaves, linear with a white line on upper surface, up to 30 cm long and 8 mm broad, and a scape of 10-30 cm. The flowers group in a corymbose raceme with 6-20 flowers, and are white with a green stripe outside.
O. umbellatum require a lot of moisture during winter & spring, but tolerate summer droughtiness. It can be grown in the woodland garden. Semi-shade is preferable. It is hardy to hardiness zone 5, and can become weedy. The plant is toxic. Used in some herbal remedies.
