Establishment (Spring)
4-6 weeks after plantingYoung plants develop basal foliage with linear leaves; growth is relatively slow in early spring
Keep soil consistently moist. Mulch around plants to retain moisture and regulate soil temperature. Do not allow to completely dry out.
Vegetative Growth (Summer)
6-8 weeksRapid stem elongation occurs; plants reach 2-3 feet tall with dense, bushy foliage. Leaves are narrow and lance-shaped, dark green in color.
Water regularly, especially during hot periods. Pinch back growing tips in early summer (before late July) to encourage bushier growth and more flower buds. Avoid overhead watering to prevent mildew.
Budding (Late Summer)
3-4 weeksFlower buds begin forming at branch tips; plants reach full height of 3-4 feet. Foliage remains lush and green.
Reduce pinching after late July. Continue regular watering but allow soil surface to dry slightly between waterings. Do not fertilize heavily as this can reduce flowering.
Flowering (Fall, September-November)
6-8 weeksAbundant rose-pink daisy-like flowers with yellow centers bloom in dense clusters. Flowers are semi-double, 1-1.5 inches across, covering the plant profusely.
Deadhead spent flowers regularly to extend blooming period and encourage more buds. Water during dry periods. Enjoy pollinator activity—bees, butterflies, and other insects visit frequently.
Senescence (Late Fall-Winter)
4-6 monthsFlowers fade and dry; foliage may show some browning. Seed heads develop and persist through winter, providing wildlife habitat and visual interest.
Leave plant standing through winter for bird food and winter interest. Cut back in early spring (March-April) before new growth emerges, or leave for late winter cleanup. Division can be done in spring.
