Dormancy/Planting
2-4 weeksBulbs are planted in fall (zones 9-11) or early spring. Bulbs appear as small, hard corms with papery outer layers.
Plant in well-draining soil. Water lightly after planting. Store bulbs in cool, dry location if planting in spring.
Sprouting
3-4 weeksGreen shoots and narrow, grass-like foliage emerge from the soil. Plants develop thin, upright stems with linear leaves.
Begin regular watering. Ensure adequate light. No fertilizer needed yet.
Vegetative Growth
4-6 weeksPlants develop taller stems (12-24 inches) with multiple narrow leaves. Buds begin to form at stem tips.
Water consistently but don't overwater. Apply balanced fertilizer monthly. Stake tall stems if needed in windy locations.
Flowering
4-6 weeksStar-shaped flowers in bright orange-red with dark centers bloom in dense spikes. Flowers open progressively up the stem over several weeks.
Continue regular watering. Deadhead spent flowers to encourage more blooms. Cut stems for arrangements. Reduce nitrogen fertilizer.
Post-Flowering/Dormancy
4-8 weeksFlowers fade and seeds develop. Foliage begins to yellow and die back. Plant enters dormancy.
Allow foliage to fully die back naturally before removing. Reduce watering significantly. Stop fertilizing. In zones below 9, dig up bulbs and store in cool, dry location.

Harvest Tips
Cut stems for flowers when the lowest buds begin to show color. Cut in early morning and place in cool water immediately. Stems will continue to open over several days indoors. For seed saving, allow flowers to fade naturally and collect seed pods once dried. Bulbs can be dug after foliage dies back; clean, dry, and store in cool (50-60°F), dark location until next planting season.
Fun Facts
