Antirrhinum hispanicum-Spanish Snapdragon

Spanish Snapdragon is also known as Creeping Snapdragon, but no where could I find propagation methods other then by seed or cuttings, but if it creeps I would assume eventually it would make another plant or why name it creeping. The thing about snapdragons is that the first year blooms aren’t as showy as subsequent years after pruning down the evergreen stems to 6" in the fall or spring. The plant is also deer and drought resistant, will bloom from late spring to fall by deadheading and prefers hot and humid summers, a native of Spain. Blooms can be either pink or yellow or multicolor.
