Dormancy & Planting
2-4 weeks until sproutingCorms are dry and dormant; planted in fall in mild climates or spring in colder regions
Store corms in cool, dry location until planting. Plant in fall (September-November) in zones 9-11; spring (February-April) in zone 8b. Soak corms 2 hours before planting to hydrate.
Emergence & Vegetative Growth
4-6 weeksSlender, grass-like leaves emerge from soil; wiry stems begin to develop with no flowers yet
Water regularly as growth begins. Apply balanced fertilizer every 2 weeks or use slow-release granules. Keep soil consistently moist. Stake tall varieties for support if needed.
Bud Formation
3-4 weeksStems elongate to 12-24 inches; flower buds form along the stem apex creating a raceme
Maintain consistent watering and fertilization. Reduce nitrogen, increase phosphorus and potassium to promote flowers. Provide sturdy support for heavy flower stems. Pinch back if stems become too tall.
Flowering
4-6 weeksStar-shaped flowers open sequentially along the stem in vibrant colors with dark centers; flowers are delicate and long-lasting
Continue watering during bloom. Deadhead spent flowers to encourage more blooms. Stake stems if needed for wind protection. Cut for arrangements to extend vase life.
Dormancy Preparation
4-8 weeksFlowers fade; foliage yellows and dies back; corms underground store energy for next season
Stop watering once flowering ends; allow soil to dry completely. Do not remove foliage until completely brown. In containers, cease watering and move to cool location. Lift corms in cold climates and store dry.
