Seed germination
7-14 daysTiny seeds germinate in 7-10 days at 65-75°F; require light to germinate, so do not cover deeply.
Keep soil moist but not soggy. Provide bright indirect light. Maintain consistent temperature. Thin seedlings if crowded.
Seedling
3-4 weeksSeedlings develop first true leaves and establish a small root system; plants are 1-2 inches tall.
Provide 12-14 hours of bright light daily. Keep soil consistently moist. Begin fertilizing at half strength every 2 weeks once true leaves appear. Avoid overwatering to prevent damping off.
Vegetative growth
4-6 weeksPlants develop multiple stems and dense foliage; become 6-12 inches tall before entering reproductive phase.
Pinch growing tips when 4-6 inches tall to encourage branching and bushier growth. Fertilize every 2 weeks with balanced fertilizer. Harden off transplants before planting outdoors. Water regularly and maintain good air circulation.
Flowering
8-12 weeks or until frostDense flower spikes form along stems, beginning at top and progressively blooming downward; flowers available in red, pink, white, yellow, coral, and bicolor combinations.
Deadhead spent flowers regularly to promote continuous blooming. Maintain consistent moisture and fertilize every 2 weeks with flower-promoting fertilizer (higher phosphorus). Support tall stems with stakes if necessary. Avoid overhead watering to prevent fungal issues.
Harvest/Post-bloom
Variable until frostPlants continue flowering but may slow in extreme heat; can be cut back in late summer for fall rebloom in cooler regions.
Cut flowers in early morning when stems are fully hydrated for longest vase life. Cut back plants by half in midsummer if growth slows due to heat stress. In mild climates, plants may overwinter for spring rebloom.

Harvest Tips
Cut flowers in early morning when stems are turgid and fully hydrated. Cut stems just above a leaf node to encourage branching from below. Cut when 50-75% of the flower spike is open for longest vase life (7-10 days). Recut stems at an angle, remove lower leaves, and change water every 2-3 days.
Fun Facts
- 🌱 Snapdragon flowers get their name from the resemblance of the seed pods to a dragon's head; when squeezed on the sides, the flower 'mouth' opens and closes.
- 🌱 The Liberty series was specifically bred for the cut flower industry and is one of the most productive snapdragon cultivars for commercial growers.
- 🌱 Snapdragons are technically short-lived perennials but are typically grown as annuals in most climates; they can overwinter in zones 9-11 and regrow in spring.
