Growth Stages

1

Germination & Seedling

2-3 weeks

Tiny seedlings emerge in 10-14 days with delicate cotyledons. First true leaves appear oval and soft.

Maintain high humidity and warm temperatures (70-75°F). Use grow lights if indoors. Keep soil moist but avoid damping off by ensuring good air circulation.

2

Vegetative Growth

3-4 weeks

Plant develops bushy, compact mounding form with green foliage. Stems become stronger and more branched.

Pinch back growing tips at 3-4 inches tall to encourage bushiness. Maintain consistent moisture and humidity. Fertilize weekly with diluted balanced fertilizer.

3

Budding

1-2 weeks

Flower buds appear in leaf axils along stems. Buds are tight and purple-tinted before opening.

Maintain regular watering and feeding schedule. Ensure adequate light (though shade-tolerant). Watch for spider mites in low humidity.

4

Flowering

12+ weeks until frost

Deep burgundy-purple flowers open, showcasing distinctive wishbone-shaped stamens in the throat. Flowers are snapdragon-like in appearance.

Continue regular watering and weekly fertilizing. Deadhead spent flowers to encourage continuous blooming. Provide afternoon shade in hot climates.

5

Late Season

Until frost

Plant continues blooming but may slow in production as temperatures drop. Flowers persist until first frost.

Reduce fertilizer frequency as growth slows. Continue watering as soil dries. Plant will decline and die at first frost unless protected.
