How to plant Ornithogalum bulbs

Depth, spacing & care (Autumn)

Ornithogalum is a graceful genus of bulbous plants known for their delicate, star‑shaped flowers and slender form. Often called Star‑of‑Bethlehem or “starflower,” these blooms typically open in late morning and close at night or on cloudy days. Their petals are white (sometimes tinged with green or yellow) and often beautifully arranged in umbels, creating a soft, celestial display in gardens.

Many species of Ornithogalum naturalize over time, spreading gradually by offsets and forming elegant clusters beneath shrubs, along paths, or in meadow-style plantings. Some types are more tender and may require protection or container growing in colder climates.

How to plant

When to plant

Plant Ornithogalum bulbs in autumn for the earliest blooms, or in early spring after frost when soil has begun to warm. Avoid planting in frozen or waterlogged soil.


Where to plant

Choose a sunny or lightly shaded location with well-drained soil. Ornithogalum grows well in borders, gravel gardens, lawn edges and containers. Avoid deep shade, which reduces flowering.


Preparing the soil

Loosen soil to 15–20 cm deep and ensure sharp drainage. Ornithogalum prefers sandy or loamy soil with good aeration. Improve heavy clay with grit or coarse sand; add light compost to sandy soil to retain moisture.


Preparing the bulbs

Select firm, healthy bulbs and plant promptly after receiving them. Do not soak the bulbs, as moisture increases the risk of rot.


Planting the bulbs

Plant bulbs 6–10 cm deep with the pointed end facing upward. Space bulbs 6–10 cm apart for small drifts, or more closely in containers for a fuller look. Water lightly after planting.


After planting

Keep soil lightly moist during the initial rooting period. Allow the soil surface to dry slightly between waterings—Ornithogalum dislikes sitting in soggy conditions.


During growth

Water occasionally during prolonged dry spells in spring and early summer. Avoid heavy fertilising; these bulbs prefer lean soil. Remove spent blooms to keep the planting tidy while allowing the foliage to photosynthesise fully.


After flowering / end of season

Let foliage yellow and die back naturally, as this feeds the bulbs for next year’s growth. In colder climates, bulbs can be lifted once dormant and stored dry, but they typically overwinter well in the ground if drainage is good.


Extra tips

Ornithogalum naturalises beautifully in lawns, meadows and gravel gardens. It pairs well with alliums, muscari, narcissus and low grasses for a soft early-spring display. Low-maintenance and ideal for drought-tolerant gardens.
