About

Ornithogalum, commonly known as star of Bethlehem, is a bulb-forming perennial within the Asparagaceae family. It features narrow, strap-like leaves growing from the base and produces racemes of star-shaped flowers, typically in white, yellow, or orange. This deciduous plant forms tufts or clumps and thrives in well-drained soils such as chalk, clay, loam, or sand. Suitable for full sun or partial shade, it prefers sheltered, south- or west-facing aspects. Hardy in UK conditions (H4 to H6), it is ideal for cottage gardens, gravel gardens, patios, rock gardens, and underplanting roses and shrubs.
