Isn't everything in Arkansas a perennial? I mean yes some plants are technically and will always be annuals, but if the environment is conducive, then the plant will live as long as it can. And that's pretty much what these snapdragons are doing. They just aren't dying. True perennials will die back and produce new shoots. These plants aren't cut back but somehow survive the harsh conditions that should kill them and continue growing. Still gonna save some seeds because it's a great bushy type of snapdragon.
