1000 Potomac Yellow Snapdragon Seeds - Antirrhinum majus for Garden & Cut Flowers

Potomac Yellow Snapdragon (Antirrhinum majus) is a classic garden favorite prized for its tall, upright spikes of bright yellow blooms. This variety produces densely packed flower spikes that open from the bottom upward, delivering weeks of color in beds, borders, and cutting gardens. The cheerful yellow flowers contrast beautifully with the deep green foliage and make a striking addition to both formal and cottage-style plantings.

Snapdragons are as useful in the vase as they are in the garden. The sturdy stems and long-lasting blooms make Potomac Yellow an excellent choice for fresh cut flower arrangements, and the flowers also attract pollinators such as bees and butterflies. Whether planted in mass displays or tucked among perennials, these snapdragons bring vertical interest and vivid color to the landscape.

Planting & Care

Start snapdragon seeds indoors 6 to 8 weeks before the last frost date. Sow seeds on the surface of a moist seed-starting mix and press them gently into the soil, as light aids germination. Keep the medium consistently moist and maintain a temperature around 65 to 70 degrees Fahrenheit. Once seedlings have developed several sets of true leaves and all danger of frost has passed, harden them off gradually before transplanting outdoors.

Choose a sunny location with well-drained soil and space plants about 9 to 12 inches apart. Water regularly to keep the soil evenly moist, especially during dry spells, and apply a balanced fertilizer if growth appears slow. Pinch back young plants to encourage bushier growth, and remove spent flower spikes to promote continued blooming. Tall varieties may benefit from light staking in windy locations.
