Light: Full sun to light shade; they need at least 6-8 hours of direct sun daily.
Soil: Well-drained, fertile, loamy soil is ideal. They may rot in heavy, wet, or clay soils.
Watering: Consistently moist soil is required, especially in spring/summer, but they should not be waterlogged. Provide 1–2 inches of water per week.
Fertilizing: Feed with a balanced, slow-release fertilizer in early spring as growth appears.
Maintenance: Deadhead spent flowers to prevent seed production. Do not cut back foliage until it turns yellow/brown in the fall, as it feeds the bulb for next year.
Division: Divide clumps every 3–4 years in the fall to prevent overcrowding and maintain vigor.
