3-4 weeksSmall rosettes of narrow, lance-shaped green leaves emerge; plant establishes root system
Keep soil lightly moist but not waterlogged; provide bright light; harden off transplants before planting outdoors
Vegetative Growth
4-8 weeksFoliage expands into dense, spreading mats; stems begin trailing or cascading; plant develops fibrous root system
Water moderately; reduce watering as plant matures; no fertilizer needed in nutrient-rich soil; trim lightly to encourage bushiness
Flowering
4-6 weeks (spring, typically April-May)Dense clusters (umbels) of tiny white, four-petaled flowers cover the plant; blooms are fragrant and attractive to pollinators
Deadhead spent flowers to encourage continued blooming; provide full sun for maximum flower production; avoid overhead watering
Post-Bloom Maintenance
Summer through early fallFlowers fade; plant continues producing green foliage; growth slows in summer heat
Prune back by one-third after flowering to maintain compact shape and encourage next year's blooms; water minimally in summer
Dormancy/Winter
Late fall through early springPlant becomes semi-dormant; evergreen foliage persists; minimal growth occurs
No watering needed; provide winter protection only in zone 3 areas; remove dead or damaged foliage in late winter
