Taxonomy Ornithogalum dubium was first described by the botanist John Gilbert Baker in 1870. The genus Ornithogalum contains over 200 species, which are distributed throughout Europe, Africa, and Asia. The name "Ornithogalum" comes from the Greek words "ornis," meaning bird, and "gala," meaning milk, referring to the white color of the flowers. Description Ornithogalum dubium is a bulbous perennial plant that can grow up to 30 cm tall. It has narrow, lance-shaped leaves that are up to 20 cm long and 1 cm wide. The plant produces multiple stems that each have several bright orange flowers. The flowers are star-shaped, with six petals that have a slight upward curve, and are up to 5 cm in diameter. The flowers of Ornithogalum dubium are pollinated by insects such as bees and butterflies, which are attracted to the bright orange color and sweet fragrance of the flowers. After pollination, the plant produces a capsule containing numerous seeds. Growth Requirements Ornithogalum dubium is a sun-loving plant and should be grown in a location that receives full sun to partial shade. The plant prefers well-drained soil that is rich in organic matter. It can tolerate a range of soil pH, from slightly acidic to slightly alkaline. Ornithogalum dubium is drought-tolerant and can withstand extended periods of dryness. However, it is recommended to water the plant regularly during the growing season to ensure healthy growth and flowering. Propagation Ornithogalum dubium can be propagated by seeds or by dividing the bulbs. To propagate by seed, sow the seeds in a well-draining soil mix in the fall. Keep the soil moist but not waterlogged and place the container in a location that receives bright, indirect light. The seeds should germinate within two to three weeks. To propagate by dividing the bulbs, wait until the plant has finished flowering and the leaves have died back. Carefully dig up the bulbs and separate the smaller bulbs from the parent bulb. Replant the bulbs immediately in well-draining soil and water thoroughly. Care Ornithogalum dubium is a relatively low-maintenance plant. Once established, it requires little attention other than regular watering and occasional fertilization. Fertilize the plant in the spring and fall with a balanced fertilizer. The plant may be susceptible to pests such as thrips, aphids, and spider mites. Regular inspection of the plant and the use of insecticidal soap or neem oil can help prevent infestations. In areas with cold winters, the plant should be protected from frost. In these areas, it is recommended to grow the plant in a container and bring it indoors during the winter months.

Its bright orange flowers and narrow, lance-shaped leaves make it a standout plant that is sure to attract attention. Whether grown from seed or propagated by dividing bulbs, Ornithogalum dubium is a relatively low-maintenance plant that can thrive in a variety of growing conditions.
