Potomac™ Dark Orange Snapdragon

Potomac™ Dark Orange is an upright Antirrhinum majus selected for orange flower spikes and cut-flower production. PanAmerican Seed identifies code PAS3439 and reports stem lengths of 39–60 inches for greenhouse or high-tunnel production. ## Flowering and cutting The [exact PanAmerican cultivar profile](https://www.panamseed.com/Products/057801176003803/snapdragon-potomac-dark-orange/) lists late spring, summer, and late summer flowering, and describes tall, strong stems with long spikes. It recommends high light, long days, and warm temperatures for the Potomac crop. The source calls the 39–60-inch measurement stem length; it is not a garden spread estimate. ## Siting and soil The breeder lists sun exposure and upright habit. For snapdragons generally, [NC State Extension](https://plants.ces.ncsu.edu/plants/antirrhinum-majus/common-name/common-snapdragon/) recommends full sun to part shade and moist, rich, well-drained soil. It notes low drought tolerance and reduced performance in summer heat; these are species-level observations rather than a cultivar-specific schedule. ## Maintenance Water near the soil line and avoid overhead irrigation. Stake tall plants where needed and watch for rust and other leaf diseases in humid weather.
