From Wikipedia, the free encyclopedia

 

Ornithogalum umbellatum, the garden star-of-Bethlehem, grass lily, nap-at-noon, or eleven-o'clock lady, is a perennial bulbous flowering plant in the asparagus family (Asparagaceae). O. umbellatum is a relatively short plant, occurring in tufts of basal linear leaves, producing conspicuous white flowers, in a stellate pattern, in mid to late spring. The flowers open late in the day (hence some of its common names), but when closed have a green stripe on the outside. It is native throughout southern and central Europe, and north-western Africa. O. umbellatum is often grown as a garden ornamental, but in North America and other areas it has escaped cultivation and can be found in many areas, where it may be considered an invasive weed. Parts of the plant are considered poisonous, but are used in some regional cuisines. Essences are also sold as patent remedies. O. umbellatum has been depicted in art by artists such as Leonardo da Vinci, and folklore has suggested it originally grew from fragments of the star of Bethlehem, hence its horticultural name.

 

Description

O. umbellatum is a perennial herbaceous bulbous plant (geophyte), dying back after flowering, to an underground storage bulb. The following year, it regrows from the often shallow rooted bulbs, which are ovoid with a membranous coat,[2] 15–25 millimetres (1⁄2–1 inch) long and 18–32 mm (3⁄4–1+1⁄4 in) in diameter. The bulbs form multiple leaf-bearing bulbils that soon separate but remain close by.[3] Initially the plant forms 6–10 basal leaves, that arise in tufts from the bulbs. The leaves are grooved (canaliculate), smooth (glabrous) and linear with a white to light green linear midrib on the upper surface, and grow up to 30 centimetres (12 in) long and 8 mm (1⁄4 in) broad.[4]

 

O. umbellatum is scapose, with a glabrous flower stem (scape) that emerges from the leaf tufts later and is about 10–30 cm (4–12 in) in height, tapering at its tip.[2]
