Growth Stages

1

Dormancy

June-October

Bulbs rest underground during summer and fall after foliage dies back.

Store dry bulbs in cool location if dug up. No watering needed during dormancy.

2

Emergence & Growth

March-April

Narrow, grass-like foliage emerges in early spring, growing 4-6 inches tall.

Water regularly as growth begins. Apply balanced fertilizer monthly.

3

Flowering

April-May

Delicate star-shaped white flowers with green-striped petals bloom in loose clusters atop stems.

Flowers last 2-3 weeks. Do not deadhead if you want seeds/naturalization. Keep moderately moist.

4

Seed Development & Decline

May-June

After flowering, seed pods form. Foliage gradually yellows and withers.

Allow foliage to die back naturally to replenish bulb energy. Reduce watering.

5

Summer Rest

June-October

Foliage completely withers; bulbs enter dormancy underground.

Stop watering; avoid disturbing bulbs. Bulbs multiply underground.

Fun Facts

  • 🌱 Star of Bethlehem is also called 'Sleepyhead' or 'Nap-at-noon' because its flowers close at midday and on cloudy days, opening only in full sun.
  • 🌱 The plant is mentioned in ancient texts and is believed by some to be the biblical 'Star of Bethlehem' that guided the Magi, though this identification is historically disputed.
  • 🌱 Once established, Star of Bethlehem naturalized so aggressively in some regions that it became an invasive species, spreading via self-sown seeds and underground bulb offsets.
