Seedling
2-3 weeksTiny seedlings emerge with rounded cotyledons, developing their first true leaves within 1-2 weeks. Young plants are delicate and pale green.
Keep soil consistently moist but not soggy. Provide bright indirect light initially, then gradually expose to direct sun. Thin seedlings to proper spacing once true leaves appear.
Vegetative Growth
3-4 weeksPlant develops bushy form with multiple stems and increasingly deep purple foliage. Growth is vigorous and compact in this variety.
Pinch off top 0.25 inches of stems weekly to encourage bushiness. Ensure consistent moisture and regular fertilizing every 2-3 weeks. Monitor for pests and maintain full sun exposure.
Pre-flowering
2-3 weeksPurple foliage deepens, stems thicken, and the plant becomes more robust. Flower buds begin forming at stem tips.
Continue pinching if you want to delay flowering and maximize leaf production. Otherwise, allow buds to develop naturally. Maintain consistent watering and nutrition.
Flowering & Harvest
4-8 weeksDelicate lavender-pink flower spikes emerge above the deep purple foliage, creating striking visual contrast. Plant remains ornamental and productive.
Pinch off flower buds if you want to extend leaf production; leave flowers if prioritizing ornamental value or attracting pollinators. Harvest leaves regularly from below developing flowers to encourage more branching.
Mature/End of Season
Until frost or season endPlant reaches full size with abundant flowers and mature purple foliage. Production may slow in fall or when temperatures drop below 50°F.
Continue harvesting leaves. In frost-prone areas, plan to replant annually. In warm zones, the plant may persist as a short-lived perennial. Deadhead spent flowers to extend bloom and leaf production.

Harvest Tips
Begin harvesting leaves when plant reaches 6 inches tall by pinching off the top 0.5-1 inch of stems. Harvest regularly (every 1-2 weeks) to encourage bushiness and prevent flowering if desired. Pinch from the top of stems just above leaf nodes. Morning harvest after dew dries yields the best flavor and aroma. Remove flowers as they form if prioritizing leaf production, or leave them for ornamental display and pollinator attraction.
