Growth Stages

1

Seedling/Transplant

3-4 weeks

Small 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

2

Vegetative Growth

4-8 weeks

Foliage 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

3

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

4

Post-Bloom Maintenance

Summer through early fall

Flowers 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

5

Dormancy/Winter

Late fall through early spring

Plant 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
