Flower for the Day Star of Bethlehem 5-2-17

This meadow and trail flower grows well in direct sun and partial shade. Star of Bethlehem  (Ornithogalum umbellatum) is a perennial which has basal leaves with a white stripe.
Stalks develop from a center of leaf rosettes which terminate in white flowers.

Each flower consists of 6 white tepals, 6 stamens, and one pistil. Petals are part of the corolla and are modified leaves which usually are colored. Sepals surround the corolla and are usually green  leaves. Tepals occur in flowers where petals and sepals are not differentiated.The stamen is the male fertilizing organ and consists  of an anther and a filament. The pistil consists of the female organs and includes the stigma, style and ovary. The stamen of Star of Bethlehem has a yellow anther at its apex and a white filament underneath.

The Star of Bethlehem is an aggressive plant. It is a member of the lily family and is related to Allium (Onion) and Nothoscordum bivalve (False Garlic). Thanks to Claire for the ID.
