Antirrhinum majus – Tetra Mix

Growing Temp 55°F – 70°F
Days to Maturity 70-90 days

Elegant, colorful, and full of charm: The Snapdragon Tetra Mix is a classic, cool-season annual known for its dense flower spikes and wide color range, including pinks, reds, yellows, whites, and bicolors. Plants form strong, upright stems topped with tightly packed blooms that add height and structure to garden beds, borders, and containers. Snapdragons are especially valuable for early-season color and are excellent cut flowers, with blooms that last well in the vase. They also attract bees and other beneficial pollinators.

Direct Sowing: Snapdragon seeds are very small and need light to germinate, so they should be surface-sown rather than buried. Sow outdoors in early spring as soon as the soil can be worked, or in late summer for fall bloom in mild climates. Press seeds gently into the soil and keep the surface consistently moist. Germination typically takes 7–14 days at cool to moderate temperatures (55–65°F). Once seedlings are established, thin to 8–10 inches apart for good air circulation and strong growth.

Early Sowing for Seedlings: For best results, start seeds indoors 8–10 weeks before the last expected frost. Surface-sow seeds on a fine, well-draining seed-starting mix and press them in lightly without covering. Keep soil moist and maintain temperatures around 60–70°F for germination. Once seedlings have several true leaves, harden them off gradually and transplant outdoors while temperatures are still cool. Space plants 8–10 inches apart.

Harvesting: Snapdragons are ready to cut when the lower third of the flower spike has opened. Cut stems in the morning for best vase life. Regular cutting or deadheading encourages additional side shoots and prolongs the bloom period. Snapdragons perform best in cool weather and may slow down in summer heat, then resume flowering when temperatures cool again.
