Establishment
4-8 weeksNew plants develop a basal rosette of large, deeply lobed leaves emerging from the ground
Water consistently and apply 2-3 inches of mulch. Avoid transplanting stress by providing shade cloth if necessary during hot weather. Keep soil consistently moist
Vegetative Growth
6-10 weeksPlant expands with increasingly larger leaves; foliage can reach 24 inches wide and tall. Dramatic color develops in variegated varieties
Maintain consistent moisture. Monitor for slug damage, especially on young foliage. Deadhead any early flower buds to encourage foliage development in first year
Bud Formation
2-3 weeksFlower spikes emerge from the center of the foliage clump as tall, erect stems topped with clusters of unopened golden buds
Continue watering regularly. Stake tall varieties if they appear to be flopping. Ensure adequate moisture during this stage
Flowering
4-6 weeksDense racemes of bright golden-yellow daisy-like flowers bloom along tall spikes, sometimes reaching 3-4 feet high. Flowers are attractive to pollinators
Deadhead spent flowers to encourage continued blooming if desired, though seed heads are ornamental. Keep watering consistent. Support taller varieties with stakes
Seed Maturation & Dormancy
8-12 weeks through winterFlowers fade and develop decorative seed heads. Foliage begins to decline in late summer as plant enters dormancy. Leaves die back completely in fall
Leave seed heads standing for winter interest and to feed wildlife. Cut back dead foliage in late fall or early spring. Apply mulch for winter protection in colder zones
