Establishment
4-6 weeksYoung plants develop shallow root systems and produce initial stems with glossy, dark green oval leaves
Keep soil consistently moist but not soggy; provide afternoon shade in warmer zones; mulch lightly around plants to retain moisture
Vegetative Growth
8-12 weeksPlants spread horizontally, creating dense trailing stems that root at nodes; foliage becomes fuller and more vigorous
Maintain even moisture; remove weeds carefully to avoid disturbing shallow roots; light fertilization monthly with balanced fertilizer
Flowering
Throughout growing season, 4-6 monthsSmall, delicate five-petaled flowers emerge in white, pink, lavender, or purple; blooms appear among foliage along stem tips
Deadhead spent flowers to encourage continuous blooming; maintain consistent moisture to support flower production; apply low-nitrogen fertilizer if needed
Maturation & Coverage
6+ months to full maturityPlant forms solid ground-covering mat, completely suppressing weeds; dense foliage creates uniform appearance
Reduce watering frequency once fully established; allow some natural spread but trim back if encroaching on other plants; fertilize lightly once or twice annually
Dormancy (in cooler zones)
3-5 months depending on zoneIn zones 4-6, foliage may die back partially or completely in winter; roots remain alive below ground
Reduce watering significantly; do not fertilize; mulch lightly for winter protection in zone 4; remove dead foliage in early spring as new growth emerges
