Star of Bethlehem
Bulbs and bulblike plants, Perennials
Clusters of typically star-shaped flowers appear on these small, grassy plants in the spring; but O. dubium may start blooming in late winter. Leaves vary from narrow to broad and tend to droop. In mild-winter areas, ornithogalums can fill many different roles. Set them in open woodlands, wild gardens, or rock gardens, where many kinds will naturalize; plant them in containers or mass them in borders.
Where cold winters prevent growing ornithogalums outdoors, plant the bulbs in pots and force them to early flowering indoors or in a greenhouse. Plant bulbs in early fall in well-drained soil amended with plenty of organic matter, setting them 3 in. deep and 3–4 in. apart. Provide regular moisture during growth and bloom. In areas with summer rainfall, grow them in pots to keep them dry. Dig and divide plantings of all species only when plant vigor and bloom quality decline.Ornithogalum umbellatum
