Vegetative
4-6 weeksPlant develops sturdy stems and deeply lobed basal foliage. Height increases to 12-18 inches. Bushy, compact form develops.
Maintain moderate watering. Apply balanced fertilizer monthly. Pinch back growing tips in early season to encourage branching and fuller shape.
Budding
2-3 weeksPurple-pink flower buds form at stem tips. Central cones become visible within the developing buds. Plant reaches near-mature height.
Continue regular watering. Reduce nitrogen fertilizer to encourage flowering over foliage. Stake if needed in windy locations.
Flowering
6-8 weeksDouble or semi-double blooms open with white-tipped pink petals and distinctive orange-brown central cone. Multiple flowers bloom simultaneously across the plant.
Deadhead spent blooms regularly to encourage continuous flowering. Water at soil level to keep flowers dry. Enjoy for 6-8 weeks of peak bloom.
Seed Production & Dormancy
4-6 weeks (end of season)If left undeadheaded, seed cones develop and mature to brown. Plant begins to decline in fall; foliage yellows and dies back to ground level.
