Vegetative Growth
6-8 weeksDeeply lobed, fern-like basal foliage develops on sturdy stems; plant grows 24-36 inches tall
Maintain consistent soil moisture. Apply 2-3 inches of organic mulch around base. Fertilize monthly with balanced fertilizer if soil is poor
Bud Formation
2-3 weeksFlower buds form at stem tips; plant reaches full height
Continue regular watering and mulching. Provide afternoon shade in zones 6-7. Remove competing weeds
Flowering
3-4 weeksDistinctive double orange spherical blooms open, held above foliage on strong stems. Flowers are 1.5-2 inches in diameter
Continue watering during bloom. Deadhead spent flowers to encourage longer blooming if desired, though some prefer to leave for ornamental seed heads. Cut flowers for arrangements in the morning
Post-Bloom/Seed Development

Reduce watering slightly if it becomes very warm. Cut back foliage in autumn after frost kills it. Plants enter dormancy as temperatures rise and daylength decreases

Harvest Tips
Cut flowers in early morning when buds are just opening for longest vase life (7-10 days). Use sharp, clean scissors and cut stems at an angle. Place immediately in cool water with floral preservative. Leave at least 1/3 of the stem on the plant to support regrowth. In cooler regions, blooms persist 3-4 weeks on the plant if left unharvested

- 🌱 The genus name 'Trollius' derives from the German word 'Trollblume' meaning 'sphere flower,' referring to the distinctive round bloom shape
