Growth Stages

1

Seedling

2-3 weeks

Small, delicate seedlings with narrow leaves emerging from soil

Keep soil moist but not waterlogged. Provide bright light. Maintain 65-70°F. Thin seedlings if crowded.

2

Vegetative Growth

3-4 weeks

Rapid trailing growth with increasingly dense foliage; stems elongate and branch profusely

Pinch back tips when 4-6 inches tall to encourage branching. Water regularly. Begin light fertilizing every 2 weeks.

3

Budding & First Flowers

1-2 weeks

Purple fan-shaped flower buds appear at stem tips; first delicate flowers emerge

Continue regular watering. Apply balanced or slightly phosphorus-rich fertilizer to encourage blooms. Ensure adequate sunlight.

4

Flowering & Blooming

8-12 weeks (or until frost)

Abundant purple fan-shaped flowers (distinctive 5-petaled form) cover plant; continuous bloom production

Deadhead spent flowers to promote more blooms. Water consistently. Fertilize every 2 weeks with balanced NPK or bloom-booster formula.

5

Decline (End of Season)

4+ weeks

Flowers slow as temperatures drop; foliage may lose vigor; plant enters dormancy

In warm zones, can continue producing blooms. In cool zones, treat as annual and plan for removal before first frost.

Common Pests

  • Spray with water to dislodge; use insecticidal soap or neem oil if severe. Maintain humidity around plant.

  • Use yellow sticky traps; spray with insecticidal soap or neem oil weekly until controlled.

  • Remove by hand with cotton swab dipped in rubbing alcohol; spray with insecticidal soap if widespread.
