Ornithogalum sardienii (WA Prohibited)

Ornithogalum sardienii is a bulbous perennial native to South Africa's Northern Cape, where it grows in sandy or stony soils in semi-arid regions. It is adapted to a winter rainfall climate, remaining dormant through the hot, dry summer months and resprouting with the arrival of cooler temperatures and seasonal rains.

The plant produces a compact rosette of narrow, channelled leaves that are often faintly lined or keeled along the underside. In late winter to early spring, it sends up an upright inflorescence bearing star-shaped, white flowers with a green central stripe on each petal. The flowers open in full sun and close in dull or overcast conditions.

This species is suited to cultivation in pots or rock garden settings where its seasonal growth and flowering can be appreciated. During dormancy, the bulbs tolerate prolonged dryness, making them well adapted to Mediterranean-type climates.

Care Tips:

• Light: Full sun is essential for flowering and healthy growth.
• Water: Water regularly during active growth; keep completely dry in summer dormancy.
• Humidity: Prefers low humidity.
• Media: Use a sandy, well-draining potting mix.
• Fertiliser: Apply a diluted balanced fertiliser every 2-3 weeks during the growing season.
• Temperature: Ideal range is 10-25 °C; protect from frost.
• Repotting: Lift and replant bulbs during dormancy, refreshing the growing mix before the next season.
