Star of Bethlehem Plant Care Guide: How to Grow and Maintain Healthy Blooms
The Star of Bethlehem (Ornithogalum umbellatum) is a charming and delicate perennial known for its star-shaped white flowers. Easy to grow and maintain, this plant adds elegance and beauty to gardens, landscapes, and indoor settings. In this comprehensive guide, you’ll learn everything you need to know about growing and caring for the Star of Bethlehem.
Plant Overview
Origin and Appearance
The Star of Bethlehem, scientifically known as Ornithogalum umbellatum, is native to Europe, North Africa, and Western Asia. It belongs to the Asparagaceae family and is well-known for its stunning star-shaped white flowers, which bloom in clusters atop slender stems. Each flower typically has six petals with a distinctive green stripe on the underside. The plant grows from bulbs and features narrow, grass-like foliage that emerges in early spring.
Growth Habits
This perennial plant is known for its vigorous growth, often spreading rapidly through bulb offsets and seeds. It reaches a mature height between 6 to 12 inches and blooms primarily in late spring. Due to its fast-spreading nature, Star of Bethlehem can sometimes become invasive if not managed properly.
Optimal Growing Conditions
Light Requirements
The Star of Bethlehem thrives in full sun to partial shade. Ideally, provide at least 4-6 hours of direct sunlight daily. In hotter climates, partial shade during the afternoon can help prevent the plant from wilting or scorching.
Temperature and Climate
This hardy perennial is suitable for USDA Hardiness Zones 4-9. It tolerates a wide range of temperatures, but grows best in moderate climates with cool winters and mild summers. Frost-tolerant and resilient, Star of Bethlehem bulbs can survive cold winters underground.
Soil Preferences
Star of Bethlehem prefers well-draining, loamy soil rich in organic matter. Maintain a slightly acidic to neutral pH level (6.0-7.0). Avoid heavy clay or waterlogged soils, as these conditions can lead to bulb rot and other issues.
Watering and Humidity
Water regularly during the active growing season (spring), keeping the soil evenly moist but not soggy. Reduce watering after blooming, as the plant enters dormancy in summer. Star of Bethlehem is relatively drought-tolerant once established and requires minimal watering during dormancy.

Seasonal Care Tips
Spring Care
Spring is the primary growing and blooming season for Star of Bethlehem. Provide regular watering, fertilize lightly with a balanced fertilizer, and remove weeds or competing vegetation around the plants. Mulching can help retain moisture and regulate soil temperature.
Summer Care
After blooming, the plant enters dormancy in summer. During this time, gradually reduce watering and allow foliage to die back naturally. Once leaves have yellowed and dried, remove them to maintain garden aesthetics.
Fall Care
Fall is an ideal time to plant new bulbs or divide existing clumps. Prepare the soil by adding compost or organic matter, and plant bulbs about 3-4 inches deep and 4-6 inches apart. Water thoroughly after planting to encourage root establishment.
Winter Care
Star of Bethlehem bulbs are hardy and typically require little winter protection. However, in colder regions, applying a layer of mulch can help insulate bulbs from extreme freezing temperatures. Avoid excessive watering during winter dormancy.
Common Issues & Solutions
Pests
Star of Bethlehem is generally pest-resistant. However, occasionally aphids, slugs, or snails may appear. Treat aphids by spraying plants with insecticidal soap or neem oil. For slugs and snails, apply organic slug bait or handpick pests during early morning or evening hours.
Diseases
Bulb rot and fungal diseases can occur in poorly drained or overly wet conditions. To prevent these issues, ensure proper soil drainage, avoid overwatering, and remove diseased or rotting bulbs immediately.

Yellowing Leaves
Yellow leaves typically indicate natural dormancy or overwatering. Allow the foliage to die back naturally after blooming, and reduce watering as the plant enters its dormant period.
Propagation Guide
Star of Bethlehem can be propagated easily through bulb division or seeds. Here’s how you can propagate successfully:
Propagation by Bulb Division
- In late summer or early fall, dig up established clumps carefully.
- Gently separate the bulbs, discarding any that are damaged or soft.
- Replant healthy bulbs immediately, spacing them 4-6 inches apart and about 3-4 inches deep.
- Water thoroughly after planting and apply mulch to retain moisture.
Propagation by Seeds
- Collect mature seeds following bloom in late spring or early summer.
- Sow seeds in containers filled with moist, well-draining seed-starting mix.
- Cover lightly with soil and keep moist until seedlings appear.
- Transplant seedlings outdoors after the danger of frost has passed.
