Sometimes called star of Bethlehem, ornithogalum (Ornithogalum) are an interesting addition to your garden with its clusters of delicate, star-shaped blooms. Depending on the species, this perennial bulb grows in U.S. Department of Agriculture plant hardiness zones 4 through 10 but can grow as an indoor plant in colder climates. The dominant bloom color is white but ranges in color depending on the species and cultivar. You can harvest these flowers and use them for long-lasting cut floral arrangements. Grow ornithogalum in a location where it will receive full to partial sunlight in well-draining soil that's rich in organic matter.
Water the ornithogalum weekly, providing about 1 inch of water a week during the plant’s active growing period. Stop watering when the bulb goes into its dormant period, which is after it stops producing flowers.
Mix water-soluble, all-purpose fertilizer with the appropriate amount of water, based on the instructions on the packet. Apply the fertilizer once a year in the spring.
Add a 2- to 3-inch layer of mulch around the ornithogalum to protect the roots from drastic temperature fluctuation while keeping moisture in. Keep the mulch a few inches away from the base of the flower and spread it out far enough so it reaches the plant’s drip line.
Cut spent blooms off the plant with a pair of pruning shears but don’t remove the foliage. Sterilize the pruning shears with a rag dipped in rubbing alcohol after each cut. Pick fallen plant matter off the ground from underneath and around the ornithogalum, and dispose of properly. This will help prevent fungal and pest problems.
