Star of Bethlehem or Sleepy dick, scientifically known as Ornithogalum umbellatum is a member of the Liliaceae (Lily family) and is related to garlic and onions. The plant is native throughout north-western Africa (i.e. Algeria and Morocco), Europe (i.e. Austria, Belgium, Hungary, the Netherlands, Switzerland, Ukraine, Albania, Bulgaria, Greece, Italy, Romania, Yugoslavia, France, Portugal and Spain) and western Asia (i.e. Cyprus and Turkey). In North America, it has escaped its cultivation as a garden ornamental and can be found in many areas. The plant has got several common names including Arabian flowers, field onions, wonder flowers, dove’s dung, bird’s milk, chincherinchee, common star of Bethlehem, nap at noon, nap-at-noon, pigeon dung, sleepy Dick, sleepy-Dick, snowdrop, snowdrops, star flower, star of Bethlehem, summer snowflake, summer snow flake and ten o’clock lady.

Genus name comes from the Greek words ornis meaning a bird and gala meaning milk for the white flowers. Specific epithet refers to the flowers being in an umbel. The common name of the plant, ‘Star of Bethlehem’, is based on its star-shaped flowers and referred to the Star of Bethlehem that appeared in the biblical account of Jesus birth. It is recorded that the Swedes have eaten this bulb in times of shortage. Round the main small bulb there are usually a number of bulbules about the size of sago grains, but only the parent bulb is enclosed in a yellowish outer skin. Some states regard them as noxious weeds & wetlands invaders. We have patches of them in our gardens that we never planted, but which we’ve made no attempt to eradicate, as they’re really quite lovely. This species is listed as a Class C Noxious Weed in the State of Alabama.

Plant description

Star of Bethlehem plant is a short, herbaceous, perennial bulbous flowering plant that grows about 0.2 to 0.3 m tall. The plant is found growing in roadsides, open forests, cemetery prairies, grassy meadows, sunny or semi-shaded banks of rivers and streams and drainage ditches, and miscellaneous waste areas. The plant thrives in moderately fertile, moist and well-drained soil. The plant has white bulb which is 15–25 millimeters (0.6–1.0 in) long and 18–32 mm (0.7–1.3 in) in diameter with fibrous roots at the base and increase to form large clumps. Each bulb can produce up to 7 secondary bulbs. The coat of the bulb is membranous. Flowering stem is leafless, cylindrical, erect and 100-300 mm tall.

Leaves

Plant has 6–10 leaves that are narrow and linear, measuring 10-30 cm (4-12 in.) long and 2-5 mm (0.1-0.2 in.) wide. The leaves form a tuft from which a scape emerges. It has a waxy surface and is dark green in color with a white mid-rib. They are hollow and tend to arch over as they grow longer.

Flower

The white, star-shaped flowers are borne on a scape that can grow up to 30 cm (1 ft.) in height, but is usually shorter. The umbel-like raceme consists of 3-10 flowers. Each flower has 6 petals and measures 1.5-2 cm (0.5-0.75 in.) in diameter. The outside of the flower is green with white margins. The flowers appear on the plant from April to May. The blooming period occurs during the late spring and lasts about 2 weeks. There is a pleasant floral scent. The flowers open during the morning and usually close by noon.

Fruit

Each fertile flower is replaced by a 3-celled seed capsule that is sub-globose in shape about 8–18 mm long. Each locule contains many black seeds. Seeds are black, oval to spherical, 2 mm diameter. Surface is rough and hairless.

Traditional uses and benefits of Star of Bethlehem plant

  • Plant’s extract is used as sedative, for the treatment of nervous breakdown, suicidal behavior in people with depression or sadness and intestinal disorders (gases).

Common star of Bethlehem plant Management

Identification and awareness of Star of Bethlehem, together with good farm hygiene, are important for handling the weed due to the limited control options available.

As spread is mostly by means of machinery, farm hygiene is imperative to prevent the spread of Star of Bethlehem. Thoroughly wash machinery when moving from areas of known infestations and avoid the areas altogether where possible, e.g. sow around infestations.

Physical removal of bulbs is the most effective form of eradication however it is only practical for small infestations. Once the infested area becomes too large for physical removal, control is very difficult. Star of Bethlehem is near impossible to control in winter crops and pastures and severe infestations are likely to need a complete crop or pasture renovation.

There are no herbicides listed for the control of Star of Bethlehem in dry land cropping systems in New South Wales. Some are registered for use in Sugar Cane in New South Wales and some are registered in Queensland for other situations however the efficacy is variable.

A small amount of research (mostly in America) has been carried out to evaluate herbicides for the control of Star of Bethlehem. The results indicate that Gramoxone® is the only herbicide to provide effective control the season following herbicide application.
