Growth Stages

Seedling

2-3 weeks

Tiny seedlings with first true leaves emerging; very delicate at this stage

Keep soil moist; provide bright, indirect light; maintain warmth (70-75°F); avoid direct sun which can scorch seedlings

Vegetative

3-4 weeks

Plant develops bushy foliage with many stems; no flowers yet; compact mounding shape forms

Pinch stem tips when 2-3 inches tall to encourage branching; maintain consistent moisture; apply balanced fertilizer every 2 weeks

Flowering

6-8 weeks (or until frost)

Delicate orchid-like flowers appear at branch tips in clusters; blooms feature contrasting throat colors and visible stamens

Deadhead spent flowers to encourage continuous blooming; reduce nitrogen fertilizer and switch to bloom-promoting formula; maintain humidity

Peak Production

4-6 weeks

Plant covered in abundant flowers; maintains full, mounding shape with multiple bloom clusters

Continue deadheading; water consistently; protect from intense afternoon sun; reduce watering slightly if stems become leggy

Late Season

Until first frost

Flowering continues but may slow in hot weather or as day length decreases in fall; plant remains decorative

Continue deadheading; water as needed; watch for spider mites in dry conditions; frost will kill the plant
