Seedling
2-3 weeksTiny seedlings with 2-4 true leaves emerge 10-14 days after sowing. Plants remain low and compact.
Keep soil consistently moist but not waterlogged. Provide bright light and good air circulation to prevent damping off. Thin or transplant seedlings when they have 2-3 true leaves.
Vegetative Growth
4-6 weeksPlant develops sturdy stems and narrow, lance-shaped foliage. Bushy growth forms with no flowers yet visible.
Water moderately and allow some drying between waterings. Begin fertilizing weekly with balanced fertilizer. Pinch growing tips once or twice to encourage branching and fuller shape.
Bud Formation
2-3 weeksTall flower spikes develop at stem tips. Small buds appear densely packed along the spike axis.
Continue regular watering and feeding. Provide full sun to support prolific flower production. Support tall stems with stakes if needed.
Flowering
8-12 weeks or longerSpikes open into dense, vibrant blue-purple flowers blooming progressively from bottom to top. Plants reach full mature height of 24-30 inches.
Deadhead spent flower spikes regularly to encourage continuous blooming. Maintain consistent watering. Reduce nitrogen fertilizer; apply lower-nitrogen formula to promote more flowers than foliage.
Extended Flowering/Decline
Until frost or end of seasonContinuous flowering from mid-summer through frost in cool climates, or year-round in warm zones. Growth may slow in intense heat.
Continue deadheading. In zones 9b+, cut back by one-third in fall to rejuvenate for next season. In cooler zones, treat as annual; pull plants after first frost.
