Calectasia cyanea, commonly known as the star of Bethlehem or blue tinsel lily, is a plant in the family Dasypogonaceae growing as a perennial herb and is endemic to the south–west of Western Australia.

Sir William Hooker says, 'We figure it on account of its great beauty, a beauty which is scarcely altered by drying, for the form and colour of both leaves and flowers is truly of that kind called everlasting; and partly with the hope that our cultivators may be induced to import this lovely plant as an ornament to our greenhouses.

[6] The specific epithet (cyanea) is from the Ancient Greek κύανος (kyanós) meaning "dark blue" referring to the flower colour.

[8] The Star of Bethlehem has a very restricted distribution in the Torndirrup National Park and Albany regions of the South West Botanical Province.

[2] Old records show it as being common in the region of King George Sound but much of this area is now urbanised as the city of Albany or devoted to agriculture.
