Seedling
10-14 daysTiny seedlings emerge with narrow cotyledons and develop small linear leaves. Very delicate at this stage.
Keep soil consistently moist but not waterlogged. Provide bright light and good air circulation. Avoid damping off by spacing seedlings and ventilating.
Vegetative
20-30 daysCompact rosettes of narrow, blue-green linear foliage form. Plant remains bushy and mounding without flowers present.
Pinch back growing tips once or twice to encourage bushiness. Begin fertilizing weakly with balanced fertilizer every 2-3 weeks. Ensure good drainage.
Budding
10-14 daysTight flower buds appear at branch tips, swelling and changing color as they develop. Foliage remains dense below flowering stems.
Continue regular watering and feeding. Maintain good air circulation to prevent disease. Do not overwater at this critical stage.
Flowering
8-12 weeks (or longer with deadheading)Vibrant bicolor flowers open with deep red petals, white centers, and distinctive dark red eyes. Blooms are fragrant and abundant, creating a striking display.
Deadhead spent flowers regularly to encourage continuous blooming. Continue weekly fertilizing with dilute balanced fertilizer. Water evenly and monitor for powdery mildew in humid conditions.
Decline/End of Season
Variable; until frostFlowering slows in late summer heat or as day length decreases. Plant may become leggy or sparse if not maintained.
Cut back spent plant by half in mid-summer for rejuvenation and second flush of blooms. In fall, reduce watering and let plant naturally senesce. Plant is typically treated as annual in most zones.
