Snapdragon 'Rocket Mix'

Rocket Mix (Antirrhinum majus)

A cheerful burst of classic colour, Rocket Snapdragon Mix brings timeless charm to early-season gardens. This well-loved heirloom-style blend produces tall spires packed with bright, semi-open blooms in pink, red, white, yellow, and coral tones, creating a vibrant vertical display that shines in both garden beds and cutting rows.

Unlike the Potomac series—bred for summer production and long-day conditions—Rocket snapdragons are Group 1–2, meaning they excel in cooler spring conditions. Expect an earlier flush of blooms on slightly looser stems, ideal for naturalistic gardens, cottage plantings, and rustic bouquets. While Potomac offers rigid elegance, Rocket leans into its heritage roots: soft, lively, and full of early-season spirit. Rocket series is also shorter than the Potomac series.

HOW TO GROW:

Indoors (recommended): For best results, freeze seeds for 48 hours prior to sowing to improve germination. Sow seeds into flats or other seedling containers 8–10 weeks before your average last frost date. Light is required for germination, so surface-sow the seeds and cover just enough to hold them in place. A very fine layer of vermiculite can be used to maintain moisture levels while still allowing light to penetrate. To avoid displacing the tiny seeds, bottom water or mist the containers lightly. Once seedlings are established, harden them off for 7-10 days before transplanting them outdoors after all danger of frost has passed.

Direct Seeding (not recommended): Snapdragons require a long, cool growing season to produce blooms. Direct seeding is generally not recommended as it often results in later, less prolific flowering.

Soil Preference and Watering: Snapdragons thrive in full sun and prefer rich, well-drained soil. Keep the soil consistently moist, especially during germination and while young plants are establishing. Once mature, water regularly but avoid waterlogging the soil.

Pinching: To encourage a bushier plant with more flowers, pinch the tops of young plants when they are approximately 4 inches tall. This will promote branching. Space the plants 4-6 inches apart to allow for proper air circulation and growth.

Fertilizing: Snapdragons are heavy feeders. Regular applications of a balanced liquid fertilizer will promote continuous blooming. Alternatively, amend the soil with compost before planting.
