Potomac Plumblossom is a refined F1 hybrid snapdragon bred for both field and greenhouse production, bringing new vigor to this classic cutting flower. Bred to grow compact and sturdy, it reaches maturity in 110-120 days and thrives in partial shade across hardiness zones 6-11. This half-hardy annual produces blooms suitable for cut arrangements and, surprisingly, for the edible flower trade, making it a dual-purpose choice for gardeners seeking ornamental appeal with culinary versatility.

Start seeds indoors 8-10 weeks before your last spring frost. Surface-sow pelleted seed into 128-cell flats or preferred seedling containers; light is required for germination, so cover seeds just enough to hold them in place. A fine layer of vermiculite can maintain moisture and prevent algae without smothering the seed. Bottom water or mist lightly to avoid displacing soil over the seed. Maintain soil temperature between 65-75°F for reliable germination.
Transplant seedlings to cell packs once they develop true leaves, then harden off by gradually exposing them to outdoor conditions over 7-10 days before final transplanting. Move to the garden after your last frost date, spacing plants 4 inches apart in partial shade.
For cut flowers, harvest stems in the morning when blooms are fully open but still fresh. Cut just above a leaf node to encourage additional blooming on lateral shoots. For edible flowers, harvest individual petals or small florets as needed; they are best used fresh shortly after picking.
Pinching the growing tips early in the season is recommended to encourage branching and a fuller, bushier plant with more cutting stems. This is especially useful if you're growing for cut flowers rather than single-stem specimens.
