Establishment
2-4 weeksYoung plants develop roots and begin sending out trailing stems with small leaves
Water regularly to establish a strong root system. Mulch lightly around plants but keep away from stems to prevent rot.
Vegetative Growth
3-6 weeksStems elongate and spread horizontally; foliage becomes denser with attractive variegation or silvery markings clearly visible
Pinch back stems occasionally to encourage bushier growth and better coverage. Ensure adequate shade and consistent moisture.
Flowering
6-10 weeks (spring to early summer, may repeat in fall)Delicate flowers in pink, purple, white, or bicolor appear along stem nodes in whorled clusters
Deadhead spent flowers to encourage continued blooming. Provide afternoon shade in hot climates to prevent stress.
Summer Rest
4-8 weeksGrowth slows in heat; foliage may pale or diminish in very hot conditions; plant enters dormancy phase
Reduce watering slightly but maintain soil moisture. Provide afternoon shade in zones 8-9 to prevent leaf scorch.
Fall Rejuvenation & Winter Dormancy
Dormancy through winter until springPlant may produce secondary flowers in cool fall weather; foliage remains evergreen in milder zones but dies back in colder areas
Cut back dead foliage after hard frost in cold zones. In mild zones, leave foliage intact for winter interest.
