A seed worth growing
Potomac Royal Pelleted (F1) Snapdragon Seed
About this variety
A tall main-season Potomac snapdragon for field or greenhouse.
Potomac snapdragons make tall, refined spikes for cutting. This one blooms deep rose.
Group 3–4 snapdragons are the warm-season types, bred to perform under long days, strong light and warm temperatures. The blossoms are edible, with a mildly bitter, floral taste; add just a few as a garnish.
Plants grow 32–48" tall and flower about 110–120 days from sowing. Pelleted seed with a conventional coating (not NOP-compliant) for easier sowing. F1 hybrid.

Know before you sow
Quick Facts
Growing times vary with weather, soil and local conditions.
Growing guide
From seed to harvestPot on
Move seedlings up at the first true leaves, about 3–4 weeks after sowing. Pinch at 4–6 leaves for more stems if you like.
Plant out
Sun to part shade in rich, moist, well-drained soil, 4–12" apart (6–12" for pinched plants).
Harvest
Cut when the lower third to half of the spike is open; hold at 32–40°F. Vase life is 7–10 days.
Growing Information
Days to germination
7–14 days at 70–75°F (21–24°C).
Starting indoors (recommended)
Sow on the surface of 128-cell trays or other seedling containers 8–10 weeks before planting out. The seed needs light to germinate, so cover it only enough to hold it in place; a very fine layer of vermiculite keeps it moist and discourages algae. Water from below or mist gently so the seed is not buried. Move seedlings into cell packs or larger pots at the first true leaves, about 3–4 weeks after sowing. Direct sowing is not recommended.
Pinching (optional)
For bushier plants with more flowering side shoots, pinch young plants back by half once they have 4–6 leaves or stand about 3–4" tall. Pinching delays flowering by a few weeks; space pinched plants 6–12" apart.
