Cultivation Methods
Hypoxis colchicifolia Baker, commonly known as the star lily, can be grown both indoors and outdoors. Choose a well-draining soil and place the plant in an area that receives bright but indirect sunlight. Propagation can be done through division or by planting seeds in spring. Ensure that the temperature stays above 50°F (10°C) and avoid exposing the plant to frost.
Watering Needs
Star lilies need regular watering during the growing season, but take care not to over-water the plant. The soil should be moist but not waterlogged as this can cause root rot. Allow the soil to dry out slightly before watering again. During winter, reduce the watering frequency and only water when the soil is dry to the touch.

Propagation of Hypoxis colchicifolia Baker
Hypoxis colchicifolia Baker, commonly known as the Star of Bethlehem, is a beautiful ornamental plant that is easy to propagate. There are two main propagation methods for this plant:
Division
Division is the easiest and most common method of propagating Hypoxis colchicifolia. The best time to divide the plant is during the spring or fall when it is dormant. Carefully dig up the plant and gently separate the tubers. Each tuber should have at least one bud attached. Replant the tubers immediately in a well-draining soil mix in a pot or in a new garden location. Keep the soil moist and wait for new growth to emerge.
Seed
Propagation of Hypoxis colchicifolia from seed is also possible, but it requires more time and patience. Collect seeds from the plant when the seed capsules turn brown and start to split open. Sow the seeds in a well-draining soil mix in a pot. Cover the seeds with a thin layer of soil and water thoroughly. Keep the pot in a warm, bright location and make sure the soil stays moist. Germination can take anywhere from 2 to 6 weeks. Once the seedlings have several true leaves, they can be transplanted to their own pots or in a new garden location.
