The breeder lists upright habit, sun exposure, and the Potomac family’s flowering season. No exact mature width is provided, so the existing numeric width remains unchanged. ## Growing conditions 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 describes Antirrhinum majus as a tender perennial often grown as an annual, with low drought tolerance and sensitivity to summer heat. These species-level notes do not define cultivar-specific garden spread. ## Maintenance Water at the soil line and avoid overhead irrigation. Harvest stems for floral use and support tall plants where wind may cause leaning. Monitor foliage for rust or leaf disease in humid weather.
