Ideal Location

This plant grows best in a sunny location with at least 5-6 hours of direct sunlight daily. Partial shade can work, but flowering will be lighter. Ensure an open, well-ventilated location. This bulb is ideal in sunny borders and cut flower gardens.

Soil

Ornithogalum pyramidale is undemanding regarding soil. The key is that soil is well-draining - good drainage is essential. Heavy clay soil can be improved with sand. A neutral to slightly acidic pH (6.5-7.5) is ideal. Ensure the plant is in a warm location in the ground.

Watering

As for watering, these bulbs are fairly drought-tolerant. After establishment, you can water less. However, ensure the soil doesn't completely dry out. Water moderately during flowering for longer bloom. After flowering, gradually reduce and stop watering.

Pruning

Pruning is not necessary. You can remove spent flowers for neatness, but this doesn't essentially affect bulb growth. Let the leaves rest quietly after flowering and yellow - they replenish the bulb.
