Antirrhinum Majus (Snapdragon) "Potomac White"
Group 3/4
If you’re looking for tall, uniform, florist-grade snapdragons, the Potomac™ series is the one to grow. Bred specifically for high-stem quality, strong flower spikes, and excellent vase life, Potomac™ snaps are a favorite among cut flower growers. They thrive in warm conditions, making them perfect for late spring through autumn production, and their long, sturdy stems make them a dream for bouquets and floral design.
 
What Makes Potomac Snapdragons Special?
  • Tall, Straight Stems – Ideal for the cut flower market.
  • Heat-Tolerant – Unlike many snapdragons that struggle in the heat, Potoma continues producing strong, high-quality stems even in summer temperatures.
  • Long Bloom Window – Perfect for mid-to-late-season production, with a steady succession of blooms.
  • Strong Stem Structure – Less prone to bending, so you get perfectly straight, elegant spikes every time.
  • Uniform Growth & Bloom Timing – This series has been bred for consistent performance, meaning plants bloom at roughly the same time and produce marketable stems week after week.

    We make every effort to provide British seeds where possible, but in some cases our British Growers are unable to grow in sufficient quantities to meet our demand or the seeds are subject to Plant breeders' rights which means it is only possible for us to buy these seeds from certain non UK flower farms
