snapdragons as perennials
Should I pull my short plants this fall or if I leave them in the ground for the winter, might they grow in the spring?
You can pull them, leave them, or harvest seeds. Most snapdragons are self-seeding annuals, so they will come back each year, but they are not necessarily going to be the same plants as the year before. There are a few varieties that are considered perennial, in Zones 9-10; however, most are not. Many of the seeds remain cold hardy to -30 so they will normally remain viable throughout winter and new plants will pop up in the spring.
