Seedling
2-3 weeksTiny seedlings with two cotyledons and first true leaves appearing. Very delicate with minimal foliage.
Keep soil lightly moist but not waterlogged. Provide bright light immediately. Thin seedlings to 2-3 inches apart. Maintain warm temperatures (65-75°F).
Vegetative Growth
4-8 weeksYoung plant develops multiple sets of narrow, lance-shaped green leaves along branching stems. Foliage becomes increasingly fragrant.
Establish consistent watering schedule. Begin fertilizing every 3-4 weeks with balanced fertilizer. Pinch back growing tips to encourage bushiness. Reduce nitrogen to avoid excessive vegetative growth.
Pre-flowering
2-3 weeksPlant reaches mature height of 18-36 inches. Flower buds begin forming at stem tips. Foliage is full and dense.
Maintain consistent watering and reduce fertilizer nitrogen. Deadhead any early flowers to encourage more blooms. Ensure adequate sunlight. Support tall varieties with stakes if needed.
Flowering
6-12 weeks or moreBeautiful tubular pink to rose flowers bloom densely in elongated spikes. Flowers attract hummingbirds and pollinators. Blooms continue for extended period.
Deadhead spent flowers to promote continuous blooming. Water at soil level to keep flowers dry. Monitor for pests attracted to flowers. Reduce fertilizing—focus on potassium instead of nitrogen.
Seed Set & Dormancy Preparation
Variable; 4-6 weeks before hard frostFlowers fade and seed pods develop. Foliage begins to decline in late fall. Plant enters dormancy in colder zones.
Allow some flowers to remain for seed collection if desired. Gradually reduce watering in fall. In zones 6-7, cut back plant to 3-4 inches above soil line in late fall. In warmer zones, can leave for partial winter interest.

Harvest Tips
Harvest leaves and flowers anytime during growing season for culinary use; early morning after dew dries is best for peak flavor. Pinch off flower clusters as needed. For drying, cut stems just as flowers begin to open, bundle, and hang-dry in a warm, airy location. Harvest seeds in late summer/early fall when seed pods turn brown; collect in paper bags as they dry.
