Snapdragon 'Potomac Ivory'

Potomac Ivory (Antirrhinum majus)

Elegant and understated, Potomac Ivory Snapdragon rises in tall, architectural spires topped with creamy, moonlit blooms. Each floret opens in soft layers of ivory and pale buttercream, creating a vertical drift of light above deep green foliage. The bloom shape is classic and refined, with a gentle flare that feels both cultivated and romantic—like an antique flower revived for the modern garden.

A Group 4 snapdragon, Potomac Ivory is bred for long-day flowering and summer production, thriving in warm, extended daylight. Stems are strong, straight, and ideal for cutting, while the soft tone pairs effortlessly with almost any colour palette—particularly dusty mauves, blushes, and sage greens. A timeless presence in floral design and garden structure.

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 4–6 inches tall. This will promote branching. If pinching, space the plants 6–8 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.
