Ornithogalum Species

Ornithogalum is a genus of bulbous flowering plants in the asparagus family (Asparagaceae), native mainly to southern Africa and parts of Europe and western Asia. The group includes many species commonly called “star-of-Bethlehem” due to their star-shaped flowers. General characteristics: Grows from underground bulbs (geophytes). Produces narrow, strap-like green leaves. Flowers are typically star-shaped with 6 white (sometimes green-striped) petals. Many species open in sunlight and close in low light or at night. Flowering season varies by species, but many South African types bloom in spring. Habitat: Found in grasslands, renosterveld, fynbos edges, and rocky or sandy soils. Many species are adapted to seasonal rainfall patterns (winter or summer rainfall depending on region). Cultivation: Prefers well-drained soil and full sun. Requires a dry dormancy period after flowering when leaves die back. Water lightly during active growth; avoid overwatering during dormancy. Bulbs can multiply over time, forming clumps. Notes: Some species are highly ornamental, while others are considered invasive outside their native range. A few species may be toxic to livestock if ingested.
