Potomac™ Lavender Snapdragon

Potomac™ Lavender is an upright snapdragon bred by PanAmerican Seed for cut-flower production. The breeder identifies PAS930436 and reports 39–60-inch stem lengths for the cultivar. ## Flowering and cutting The [exact PanAmerican cultivar profile](https://www.panamseed.com/Products/057801176002843/snapdragon-potomac-lavender/) lists late spring, summer, and late summer flowering and recommends greenhouse or high-tunnel crops. Potomac performs best during high-light, long-day, warm production periods; the source’s 39–60-inch measurement is stem length rather than 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; this broader species guidance is not a cultivar-specific growing schedule. ## Maintenance Water near the soil line and avoid overhead irrigation. Stake tall plants where needed and monitor foliage for rust and other leaf diseases in humid weather.
