A new and distinct cultivar of Ornithogalum thyrsoides Jacq. named ‘Bethlehem’ originated as a controlled cross between the commercial cultivar Ornithogalum thyrsoides Jacq. ‘Chesapeake Snowflake’ and an unnamed Ornithogalum thyrsoides Jacq. cultivar. The cultivar ‘Bethlehem’ has R.H.S. 155 C (white group) tepals at maturity and is distinguished from other similar cultivars of which the inventor is aware by its tall racemes, wide leaves and suitability for growth in pots.
