A new and distinct cultivar of Ornithogalum dubium named ‘Lourdes’ originated as a controlled hybridization that started with the crossing of the commercial cultivar Ornithogalum thyrsoides Jacq. ‘Bethlehem’ and an unnamed Ornithogalum dubium cultivar. Progeny of this cross were then crossed back to the Ornithogalum dubium until the present variety was selected. The cultivar ‘Lourdes’ has R.H.S. 25A (orange group) tepals at maturity, erect and strong racemes which resist bending under low light conditions, a long blooming habit and broad, channeled leaves.
