Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge with cotyledons and first true leaves appearing within 1-2 weeks

Maintain consistent moisture and warm temperatures (70-75°F). Provide bright light. Keep soil surface moist but not soggy to prevent damping off.

2

Vegetative Growth

3-4 weeks

Plant develops trailing stems with small oval leaves; begins to fill out in containers or garden beds

Pinch back growing tips early to encourage bushier, fuller growth. Begin feeding with dilute liquid fertilizer every 2 weeks. Maintain consistent watering.

3

Flowering Initiation

1-2 weeks

Small fan-shaped flower buds appear at stem tips; purple coloring becomes visible

Reduce nitrogen fertilizer, increase phosphorus to promote blooming. Continue regular watering. Remove any dead leaves or stems.

4

Blooming

4-6 months (late spring through fall)

Distinctive five-petaled fan-shaped flowers in shades of purple open continuously along trailing stems

Deadhead spent flowers to encourage continuous blooming. Feed every 2-3 weeks with balanced or bloom-promoting fertilizer. Water regularly, especially in containers.

5

Decline

Variable, until frost

Flowering slows as temperatures cool in fall; plant may die back in frost or lose vigor indoors over winter

In frost-prone zones, treat as annual and remove. In frost-free zones, can cut back and overwinter for next season. Reduce watering and feeding.
