Key Facts
- A bulbous perennial that naturalizes from bulblets
- Produces clusters of white star shaped flowers with a green stripe on the back
- Typically flowers in spring
- Spreads slowly to form colonies and can be invasive in lawns and natural areas
- Prefers well drained soil and tolerates average garden soils
- Grows in full sun to part shade
- Bulbs and plant parts are reported as toxic if eaten
Star of Bethlehem is a small spring‑flowering bulb gardeners notice for its white star shaped blooms and its habit of naturalizing into colonies. Find out how to identify the plant, decide whether it belongs in a lawn or border and to learn how to limit its spread and toxicity risk.
Identification
Look for clusters of white, star shaped flowers often with a green stripe on the back of the petals. Flower stems are short, typically 6 to 12 inches tall. The plant grows from bulbs and produces many bulblets that form clumps over time.
Where to grow and best uses
Grow Star of Bethlehem in beds, naturalized drifts or lawns where spring bulbs are acceptable. It does best in full sun to part shade and in well drained garden soils. It is commonly used in naturalistic spring displays rather than formal container plantings.
Hardiness and bloom time
Hardiness is commonly reported as roughly USDA zones 5 to 9, though regional variation is likely. Bloom occurs in spring, commonly April to May in the Northern Hemisphere, with timing shifting earlier in warmer climates and later in cooler ones.
Soil, light and watering
Star of Bethlehem prefers well drained, moderately fertile soil and tolerates average garden soils. Poor drainage and waterlogged conditions can cause bulb rot. It flowers best with good spring sun but tolerates some shade.
Water moderately in active growth. Excessively wet soil in winter increases the risk of bulbs rotting. In summer the foliage dies back and plants require little to no irrigation.
After flowering care
Allow foliage to yellow and die back naturally before removing it. This lets the bulb store energy for the next season. Avoid cutting the leaves while they are still green.
Spread and managing naturalizing colonies
Star of Bethlehem spreads by bulbs and bulblets and can slowly form dense patches in lawns and beds. Spread is generally gradual but can increase over several years as offsets accumulate. If you do not want it to naturalize, remove bulbs and bulblets by lifting and dividing clumps after the foliage dies back.
Propagation
Propagate and control by dividing bulbs and separating bulblets. Seed spread is possible but less important for rapid colonizing than bulblets. Wear gloves if you have sensitive skin when handling bulbs.
Toxicity and safety
Bulbs and other plant parts are reported poisonous if eaten. Ornithogalum species have been implicated in livestock poisoning and may be harmful to pets and people if ingested. Consult your local poison control or a veterinarian for specific risk and guidance.
Frequently asked questions
- How fast does Star of Bethlehem grow?
- It spreads slowly by bulblets and tends to form colonies over several years. Rate of spread varies with site conditions and how often offsets are left in place.
- Is Star of Bethlehem invasive?
- It can naturalize and form dense patches in lawns and natural areas. Check local invasive species lists before planting and remove bulblets if you want to limit spread.
- When should I lift or divide the bulbs?
- Lift or divide bulbs and bulblets after the foliage has died back and the plants are dormant. This makes it easier to separate offsets and reduce colony size.
- Are the bulbs poisonous to pets?
- Bulbs are reported toxic if eaten and likely pose a risk to pets. Contact poison control or your veterinarian for local, species specific advice.
