Sternbergia lutea
flowerSternbergia is a small, autumn-blooming bulb that produces bright golden-yellow, crocus-like flowers in fall. Native to the Mediterranean region, it brings cheerful color to gardens when many other plants are fading. The flowers resemble delicate lilies and are often mistaken for crocus by gardeners unfamiliar with the genus.

Dormancy
June-AugustBulbs rest underground during winter and early summer with no visible growth
Keep soil relatively dry during summer dormancy. Ensure excellent drainage to prevent rot. Do not disturb bulbs.
Sprouting
Late August-SeptemberNarrow, grass-like green leaves and flower buds emerge from soil in late summer
Begin regular watering as growth resumes. Apply balanced bulb fertilizer. Ensure good drainage to prevent bulb rot.
Flowering
September-October (4-6 weeks)Golden-yellow, trumpet-shaped flowers bloom on short stems above emerging foliage. Each bulb produces 1-3 flowers.
Deadhead spent flowers to encourage repeat blooming. Maintain consistent moisture. Protect from heavy rain if possible.
Foliage Development
October-AprilLong, slender, rush-like green leaves continue growing through fall and into spring, reaching 12-18 inches tall
Allow foliage to grow fully; it powers the bulb for next season. Water moderately. Fertilize with bulb food.
Decline & Dormancy
May-JuneFoliage yellows and dies back as summer approaches; bulbs prepare for summer rest
Gradually reduce watering as foliage withers. Do not remove leaves until completely brown. Stop watering in early summer.

Harvest Tips
Sternbergia is primarily grown for ornamental flowers; cut flowers last 7-10 days in a vase with fresh water. Allow all foliage to die back naturally before removing it to support bulb vigor next season. Divide overcrowded bulbs in summer dormancy (June-July) every 5-6 years.
Fun Facts
